3 Insider Tips for Buying Test and Measurement Equipment

Written by oneself on 5:05 AM

By Richard Volpi

Often purchasing an oscilloscope, power supply, signal source, spectrum analyzer or some other piece of test equipment can be daunting. In 50 years of experience in the industry we’ve identified a few common pitfalls, and we have a few tips to help you avoid them.

1) Buying test equipment can be compared purchasing a car (something that nearly everyone can identify with). Equipment can depreciate quickly; consequently, one can usually find used equipment for a fraction of the price of new. Many companies also offer rental, lease, and trade-in programs. Used equipment can be tested and calibrated to the Manufacturers’ standards, just like it was when it left the factory. Often this equipment is not cosmetically perfect, but you will pay significantly less for pre-owned equipment.

2) Requesting quotes from multiple dealers may drive up your price rather than saving you money. Everyone is buying from the same pool of equipment. So when several brokers are looking for the same unit, demand artificially increases and the price skyrockets. One should definitely still do his research to ensure that he is paying a fair price, but be aware that requesting a quote from several competing dealers can increase your cost.

3) Make certain that you aren’t buying more than you need. Would you buy a Ferrari to drive around your neighborhood at 25 MPH? Do you need a huge industrial sized server to access the web, and store personal documents? Of course not, but people make a similar mistake all the time when purchasing test equipment. A 500 MHz scope may be more than enough for you, but if you aren’t careful you may become a victim of up-selling.

In short, if you want to save money when buying Test Equipment:

#1 Buy used if you can
#2 Don’t request quotes from too many broker/dealers
#3 Don’t buy more than you need

As The Fax Machine Dies

Written by oneself on 9:35 AM

by: Ajeet Khurana

Have you ever found yourself wondering how offices ever functioned or operated without the use of the fax machine? Today this technology is so common in every workplace that it has become of the essence. A business without a fax machine in today's world would be the equivalent of a middle-class family that avoids using a telephone. Communication would be slow, at best, and any business attempting to forego this expense, would very quickly lose out as rivals edged them out.

Today the fax machine isn't just a fax machine, and technology is not stopping its expansion to bring newer communication methods into the business sector. The fax machine should soon become as outdated as the record turnstile. Why is this? Because the Internet has launched a global revolution that is making it possible for every organization to let their work go on the net. That's right. Services and products are expanding at such lightening speed, that even something as simple as sending a fax may be carried out by simply clicking on a mouse.

Online faxing is a means of using the Internet and your email and their corresponding attachments to send out faxes to distant clients. Like an ISP, you must get a user ID with an online fax service to get your fax number. Once you have installed the necessary software (software, not equipment) you can fax directly from your computer in quite the same way as you would from your fax machine.

This mode of faxing is so revolutionary that many businesses want more of this technology. The convenience and simplicity that online faxes offer is being so highly appreciated that fax machines have to pack up and leave now. Moreover, many cellular phone providers are offering the same service so that you can use your cell phone as a hand-held wireless browser and send faxes from it. Imagine sitting in traffic wondering how you will reach on time. This stress could be eliminated if you fax your project over by pressing "send" on your mobile phone.

The advantages of online faxing have been multiplying. Your business will no longer require the expense or bulk of an extra phone line. Gone are the days of hold signals, wrong numbers, or busy signals. The mobility of Internet faxing makes faxing as easy as ABC. And ultimately, when you weight the costs of your fax machine and annual phone bills, Internet and online faxing has to be a great solution to all kinds of business communication issues.

Why People Can't Call Your Cell Phone

Written by oneself on 5:27 AM

by Shawn B.

This is one of the most misunderstood problems by clients and customer service reps alike.

Most of the time, when a person hears that their friend can't call them, they twist the issue around and say "my phone can't receive calls".

Let's be clear about something: if you try to trouble-shoot this from a "can't receive calls" viewpoint, you are going to arrive at the wrong conclusions. Not receiving calls is a passive problem and if you think that way, you have a bit of a victim-mentality, but that's another subject for another day.

Not being able to make calls is an active problem, and THAT is always where you want to start your trouble-shooting investigation.

KEY POINT: Whoever can't make the call is the party that investigates the issue.

Burn this phrase into your brain. Ninety-nine per cent of the time, the origination point of the problem is also the cause of the problem. So if a land line can't call a cell phone, the owner of that land line needs to call their provider. If another cell phone can't call your cell phone, that friend of yours needs to call their provider. It's so simple, yet no one gets it.

Now, it IS true that sometimes the problem ends up being on the receiving network's end...and sometimes the problem is with some third party that is carrying the land line or long distance traffic, but the only way that is going to be determined is if the originating network duplicates the call and then traces it to the sticking-point.

Possible Sticking-Points:

1) The originator could be pointing the call to the wrong switch, CLLI, point code, etc. They could also be pre-pending the wrong digits. They're not doing a dip. Usually you'll hear some kind of an error message. Pay attention to which phone provider is giving the error message.

2) There may not be enough trunks or T1's between the two (or more) networks. In this case, the caller might hear an intermittent "fast-busy".

3) In a lot of cases, if your number range is brand new and just got released, some networks are too stupid, inept, or lazy to load the range into their translations tables. This is silly, considering the phone networks are alerted months before a new line range is due to go live!

There are other reasons for these problems, but the best way to get them solved is for the originator to call their provider. TIP: when the originator calls into their customer service department, they should just say "I can't call such-and-such number". Do NOT say the name of the provider who owns the number you're trying to call. Too often, the untrained service rep, who is probably penalized for logging trouble-tickets, will say "Oh, you can't call such-and-such? Well, then, it must be their problem."

I don't know what it is, but when service reps hear the name of another provider, they get stupid all of a sudden and start pointing fingers away from the obvious source of the problem.

I hope those reps get to read this article.

In the end, whoever can't make the call MUST force their provider to log a ticket. If it's your friends, clients, or family members that can't call YOU, and THEY don't want to fix the problem, you're kind of trapped, aren't you? Do you call your cell phone provider and yell like a maniac, saying "Fix it!"? Think of the situation you've just made for the service rep you just spoke to; you've told them to go find out what provider your friend/client/family member is on, and potentially what long distance provider they're using, and to then start calling around that company in order to fix a problem that your friend, client, or family member should have done themselves. Now there's TWO MIDDLE MEN (you and the service rep) trying to work on the problem that you shouldn't be involved in.

Why not just ask the janitor there to handle it?! They're just as close to the problem as everyone else in the middle!

In the end, I want you to remember one thing:

Whoever can't make the call is the party that investigates the issue.

The Rise and Rise of Rise of Ink Jet Refills

Written by oneself on 7:03 PM

Niall Roche

Inkjet refills. What was once a messy, dangerous process has become safer and cleaner. No longer do you need to wade elbow-deep in ink through the process of topping up your empty inkjet cartridges. Not at all. Today the process of refilling your own empty inkjet cartridges is far more straighforward. And not nearly as messy.

As with most things the earliest versions of the inkjet refill kit were not perfect. They leaked, the ink was of poor quality and the instructions provided were usually substandard if you were lucky and non-existent if you weren't.

How things have changed. Ink jet refills have moved from the back pages of computer magazines to our malls and high street stores. What was once a back street business reserved for the geeks of the world has moved into the mainstream and is now socially acceptable and being franchised by new companies every single day.

Improvements in the refilling technology of both home and industrial units combined with drastic improvements in ink quality and the much lower cost of inkjet refills has led to a mini-boom in the cheap inkjet cartridge market.

The most forward-thinking of these refill companies have even started to graduate the difficulty of the ink jet refill kits you can buy. Many stores, both on and offline, are now stocking Beginner, Intermediate and Advanced inkjet refill kits. These are specially designed to exactly match the skill level of the user.

Competition in the inkjet refill market is fierce. Companies are pulling out evert stop to grab their share of what is an extremely profitable market. This competition is great news for the consumer with free shipping and excellent customer service now becoming the norm as opposed to the exception.

Ink jet refills are here to stay. The company names and brands might change but ideas and creativity won't. Why not start saving on your printer costs today?

If you're looking for discount ink jet printer refills or other ink jet printer cartridges then visit Inkjetables dot com for all your inkjet needs.

Does Your PC Take a While to Warm Up?

Written by oneself on 4:01 PM

By Zach Hope

Some people still remember the day when switching on your television set took a good couple of minutes. You couldn’t just turn on and start watching straight away – you had to plan ahead or you would miss the beginning of your favourite TV show.

We take it for granted nowadays that TV sets are ready to go at the touch of a button and with a mere second or two we have a picture with sound.

This improvement has been made possible due to the fundamental changes in the way that your TV works. Sets used to have so called “valves” that needed to be warmed up in order to work properly. The modern boxes use different technologies that don’t need to warm up.

Although our TVs get going almost immediately, the same can’t be said for our computers. Booting up windows is the modern replacement for waiting for a TV set to warm up. And they call it progress. Tut, Tut.

Back in the day there wasn’t much you could do to help speed up the warming up period, it was just considered a convenient time to go and put the kettle on. However, with your computer it is slightly different. The computer isn’t actually warming up as such, its running computer code commonly known as ‘Windows XP’. Most importantly, unlike an old telly there is something you can do to help reduce the time it takes to start up.

By making the booting process more efficient you can reduce the start-up time by up to 4 times. Computer tech guys can do this for you, but they charge a premium. Baring in mind how simple it is once you know these “secret” tips – I would recommend a DIY job. Anyone can do it, it takes a few minutes to do and will save you a lot of time and frustration in the long run.

Comptia Network+ Certification Exam Tutorial: Hubs, Repeaters, Bridges, And Switches

Written by oneself on 10:12 AM

By: Chris Bryant

To pass your Network+ certification exam, you must know the differences between hubs, repeaters, bridges, and switches. The differences are straightforward for the most part, so let's examine the basic purpose of these devices.

Hubs and repeaters both work at the Physical layer of the OSI model. They do not help to direct traffic toward the proper destination, as routers and switches do. Their purpose in the network is simply to make the signal strong enough to reach its destination, by regenerating the signal. Hubs and repeaters both take an incoming data signal and make a clean, strong copy of the signal. Otherwise, the signal would suffer from attenuation, the gradual weakening of a signal as it gets farther and farther away from the source.

Repeaters are just about extinct in today's networks, because they only have one input port and one output port. Naturally, this means we could only regenerate a single data signal. Hubs are really just multiport repeaters, but their multiple ports give them some value in today's networks.

By using a hub to connect hosts, we're left with one collision domain. Any data sent by these hosts is subject to colliding with data sent by another host. We'll talk more about collision domains in another CompTIA tutorial, but keep in mind that hubs do not break them up.

Using a hub also results in one broadcast domain, since a broadcast sent by any of these hosts will be heard by all other hosts.

Bridges and switches work at the Data Link layer of the OSI model, making them "Layer Two" devices. Both read MAC addresses to create a MAC address table, which allows the switches to help send frames to their proper destination. You see very few bridges in today's networks, especially with the advent of Layer Three switches.

It's not that bridges are bad at their job, it's just that switches are better. They can operate at higher speeds and offer more options, especially now that many new switches can perform routing as well as switching. (Layer Three switches used to be called brouters, but as the usage of bridges has faded, so has the use of this term.)

There are two rather confusing facts regarding switches that confuse many newcomers, and I want to mention them again here. First, MAC addresses are also called physical addresses because they physically exist on the network interface card (NIC). They have nothing to do with the Physical layer of the OSI model.

Second, you're going to hear several different names for the MAC address table throughout your career and your networking certification studies.

MAC address table

bridging table

switching table

physical address table

Layer Two address table

They're all the same thing! But no matter what you call it, you should know how switches build this table and use it to determine the appropriate action to take with incoming frames. A switch is either going to forward, flood, or filter a frame, depending on whether it knows how to reach the destination MAC address of the frame. We'll look at that process in the next CompTIA Network+ certification exam tutorial! See you then!

What will PCs be like in 20 Years Time?

Written by oneself on 4:27 AM

by Zach Hope

As far as I'm concerned, today's PC user falls into two camps; the savvy user and the non-savvy user. Whereas the savvy user might browse the internet with the Firefox browser and search using Google, the non-savvy would consider Internet Explorer was the internet and search using the default 'Live Search'.

The savvy would spot a virus in an email a mile off, whereas the non-savvy would curiously open it. The savvy user keeps an ear open for all the latest buzzwords; the non-savvy is confused by the same terminology. The savvy user can access their whole music collection on their computer; the non-savvy uses a completely different stereo player.

Operating systems in general have to satisfy both types of user as best they can. Microsoft has both Pro and basic versions of Windows, which reflects this need. Over the next few decades the mainstream PC user will become increasingly more familiar with more complicated, feature-rich interfaces.

To use an analogy; let's observe the Star Wars character Anakin Skywalker. If I remember correctly, in The Phantom Menace he was a kid genius, capable of making androids and flying land speeders at break-neck speeds. The way that I perceive Jedi Knights is probably the similar to the way non savvy users might perceive the savvy user. The savvy user can seemingly will the computer to do just about anything they wish in next to no time - something the non-savvy only wishes they could do.

Perhaps there will always be these two types of user; new generations and new abilities will make the once savvy user into a non savvy one. Just imagine what Windows may be like if they were adapting it for the likes of Anakin Skywalker? One can only imagine....

I personally like to see a computer that was not merely ultra portable, but was actually wearable. I would like this to take the form of a pair of spectacles that would enable the wearer to see a floating computer screen, floating in the air 3 feet in front of them. Then if it could read your brainwaves and in an instant convert it into a Word document - I think that would be pretty convenient....

Booming Chinese Telecommunication Market

Written by oneself on 9:42 AM

China now has the world's largest, and one of the best, wire-line and wireless networks. The China telecom industry is seen to have remained resilient as well as active although the global telecom industry has been moody. With China's entry into the WTO and the upcoming 3G-license release, China's telecom operators have to be more creative and innovative in order to deliver additional sophisticated services that meet the growing market requirements.

The Chinese telecom market has witnessed remarkable growth in the past five years, thanks to the economic and industry reforms of the Chinese government. The accelerated telecom industry reforms during the past decade and also completely changed the competitive landscape of the Chinese carriers market.

China's telecommunication market is boasting the greatest number of mobile telecom subscribers in the world. The market would continue to grow in 2006 while witnessing a fiercer competition among carriers and vendors. China is a country where the government's influence on and interference in the telecom market is quite strong.

The booming and rapidly transforming Chinese telecommunication market will open considerable alternative business opportunities to telecommunication's companies worldwide.

Chinese telecom carriers are now in a process of shifting their focus from infrastructure development to network improvement and value-added service development. The operators are expected to become more and more cautious about investment, including investment in the 3rd generation of mobile communications (3G) and the deployment of other new technologies.

There is increasing competition among the national telecom carriers to better serve the growing telephone subscriber base. Chinese telecom carriers have prompted debate on the future prospects of the Chinese telecom market. Although some analysts continue to believe that the Chinese telecom market is still a land of gold, others argue that the growth of telephone users will soon reach a ceiling and opportunities in the Chinese telecom market are disappearing.

The Secrets To Avoid Data Recovery

Written by oneself on 4:45 AM

Data recovery is a process whereby you can save data and files you accidentally deleted, had eaten by malicious software or viruses, hardware failures, corporate espionage and many more scenarios. Data recovery is a tricky thing, and if you've somehow deleted or had your important files corrupted or lost due to human error, business espionage, faulty hardware or software or any other reason; the good news is that your lost data is probably recoverable. When you discover that you have suffered some data loss, the first decision is always if data recovery is possible. One of the most common questions about data recovery is “why is it so expensive" and if you use software it doesn't have to be.

There are many types of data recovery software to choose from. Software programmers recognize the importance of data files, and thankfully, they have been able to create products that demonstrate their understanding of how often people accidentally delete or lose important data. Recovering or salvaging the data from media can sometimes be performed using simple hardware or software but may occasionally require the assistance of data recovery specialists. Software can recover your file allocation table in FAT, master file table and partition table in NTFS file system. Sometimes, even the so called "soft errors" can be fixed using data recovery software.

Losing your files is something that is going to happen to you one day, not something that might happen, and if you do not backup your drive you will find yourself in a very unfortunate situation.

Have a disaster recovery plan, do frequent backups. Test that your backups work and can restore your systems to a fully working condition. Hard drive failure is especially disastrous for smaller companies working with a single server and a single disk, if they do not have a complete and working data backup at hand. Having an online backup system will save your day should your premises ever burn down, or the fireproof box containing your backup disks get stolen. Online backup is possibly the most convenient form of backing up files, leaving you with few excuses not to do it. If you have ever wondered about the importance of keeping a backup, imagine how you would feel if a virus destroyed the contents of your hard drive.

Whether you’re an individual or a large corporation, sometimes data recovery is the only way (if you didn't do your backups). Physical data recovery is simply the extraction of the raw data from a damaged disc; logical data recovery means the rebuilding of damaged data files but if you are so fortunate that can see your deleted files then data recovery is quick and easy.

Monitoring Temperature And Humidity Inside The Server Rack

Written by oneself on 6:18 PM

By Mike Jarrett

The increased utilization of blade servers has caused the control of heat and humidity in the server racks to become much more critical than previously. These units increase the density of the equipment in each rack and therefore the heat generated. Alarms are necessary at the rack level because a single server overheating will not raise the ambient room temperature enough to set off the room alarm sensors. These rack alarms can provide early problem warning and prevent server damage and the associated network problems in a timely fashion.

These alarms can be at the rack, or by email, or by SNMP traps, or by all three methods depending on the system. There are several different types of sensor systems from several different manufacturers, available at present. One of them is a compact environmental monitor with one onboard temperature sensor and in addition the ability to support up to 16 remote sensors. The system is very small so you don’t have to change your system. If you receive a problem alert, you are able to identify the rack and power strip having the trouble, and turn off the individual outlet or reboot it.

Another power management and control system available is able to track temperature, humidity, airflow, and water at various locations from 15 to 100 feet away. This system needs only limited rack space and can control individual power receptacles. Another system on the market utilizes two sensor probes in each rack, one in front, one in back, to better measure the environment in the rack. This gives you a thermographic view of the temperature range in the rack and can be displayed in color for all the different racks in the computer center. This information can be used to determine the size and location of any additional A.C. or fans or blowers needed to correct a cooling system. It can also assist in the rearrangement, if necessary, of the rack layout and separation of a cold aisle/hot aisle system or any rack system, or when additional racks are added to a functioning system.

The control of heat generation and temperature in the data center continues to be one of the most critical areas. The monitoring of the environment has gone from the room, to the zone, to inside the individual server rack to give a much more precise picture of what is happening and allow better response to emergency conditions.

Poor Computer Performance - 9 Free or Inexpensive Fixes

Written by oneself on 5:08 AM

by Jed Jones

Poor computer performance by your Windows-based machine can sneak up on you gradually. You may find its performance deteriorating increasingly until one day you realize you must fix it or buy a new one. Signs of poor performance can include applications running very slowly, programs closing or freezing up suddenly, and a generally slower response time to OS (operating system)-related commands. I have compiled 9 fixes for you here that you can leverage right now to greatly improve your computer's performance.

Fix #1: Download and run MS Service Pack 2:

Every operating system requires patches and upgrades by its maker from time-to-time, with Microsoft XP being no exception. While Service Pack 2 was released in 2002, some people with older systems are still not running it: make sure your computer is. You can download it FREE from Microsoft's Web site at: http://www.microsoft.com/downloads/.

Fix #2: Run the Disk Cleanup utility:

Your computer likely has a number of unused and unneeded files that take up valuable space on your hard drive and slow performance. Run your FREE, built-in Disk Cleanup utility to automatically remove these files. Find it by going to: Start | Programs | Accessories | System Tools | Disk Cleanup and following the prompts.

Fix #3: Defragment your hard drive:
Over time, your computer will store files in an increasingly inefficient manner on your hard drive, affecting file retrieval times and other performance factors. To fix this, you need to defragment your hard disk drive. To do this for FREE, just go to: Start | Programs | Accessories | System Tools | Disk Defragmenter. First, highlight the drive you want to clean up (e.g., C drive) and choose Analyze. Once complete, choose Defragment. Note that the defragmentation process could take up to an hour or more, so do this during a time when you can step away from your computer.

Fix #4: Run an anti-virus tool:

Computer viruses are malicious programs that drastically affect your computer's performance, either all at once or insidiously over time. You can stop a virus attack by installing and running anti-virus software which performs regular scans, locates the offending viruses and quarantines them. Symantec's world class antivirus tools are an excellent choice and you can find them at http://www.protected-now.com.

Fix #5: Clean your registry:

Your computer's registry is a tool that most non-computer specialists never see but which is vitally important to computer operations. Your registry stores settings and options for your hardware, operating system, and other software. Unfortunately, given its fundamental role in the performance of your system, your registry is often the target of attack or infection. To thoroughly and automatically clean your registry, run a regular registry scan using a registry cleaning tool. I recommend RegCure, which recently found 1,626 problems with my registry (ugh!), is cheap and easy to use. Download your copy now at http://www.i-feel-great.com.

Fix #6: Run anti-spyware software:

Spyware is computer software that installs itself in your computer and performs a number of unwanted functions, including monitoring your computer usage and interfere with your control. It represents a real threat and has become a significant problem in recent years. Fortunately, fixes are easy to find and include a number of free and inexpensive anti-spyware programs.

Build Your Own Notebook

Written by oneself on 5:44 AM

By: Roberto Sedycias

The notebook is a fantastic accessory in modern life, used both for work and for play. It has the ability to produce and store a wide variety of high quality documents, play top quality games, download and run films, utilize the internet and also run business quality software essential for presentations and productivity in the modern business world. The device is designed to be portable, functional and meet the requirements of a busy modern life. However, the type of notebook chosen affects the usability levels. Many features are an unnecessary addition, depending upon what the notebook is used for. Though the quality of the machine may be unbeatable, it may not necessarily fully meet your requirements.

For instance, if the notebook is used by a travelling businessman then it needs to be highly portable. The device needs to be used in a variety of scenarios and places, and must perform to the utmost standard each time. Many elements can affect the portability of a notebook such as screen and product size, inbuilt systems and processor size. A 12 to 14 inch screen should be big enough for the travelling businessman, and the DVD player can be bought as an attachment for when it is required rather than being inbuilt. This will keep the weight of the device at the lower end and make it more accessible for travel.

If the notebook is used for recreational purposes only then portability is less of an issue whilst graphics performance and memory space become much more important. In this instance the size of the device, the graphics card, and inbuilt DVD player and rewriter will affect the choice. Also the screen will need to be at the larger end of the scale to enable better quality gaming and cinema experiences.

The notebook is generally sold with either scenario in mind, and the standard range is fantastic. But what if these general features do not fit your requirements? Every user is unique, and in the modern age people are used to being able to receive bespoke products and services. For instance, a business man may need excellent DVD features for presentations, yet still have portability a key concern. In this scenario, the best option is to build your own notebook.

To build your own notebook, you simply choose a supplier that will combine the elements that you need to create a bespoke notebook. This is usually an online provider as they can react better to supply and demand. Physical shops do not have such a good market for this type of service, as consumers go by sight to a large degree when physically shopping. A notebook in pieces does not look very attractive.

Building your own notebook entails knowing exactly what you want from your machine, so make sure you do your research and fully understand what the different elements are and whether they fit your purpose. However, it is not an option only for the completely computer literate. All sites that provide this service will be easy to navigate, with in depth explanations. The customer support team is also trained to be able to assist you with this type of information. They will be able to explain different components and also advise whether your choices will be beneficial to your needs. The notebook builder will put together all the required elements, to create a machine that will provide the optimum performance for you.

The price of your tailor made notebook will depend upon the components that you require, rather than an overall predetermined cost. Therefore, it will completely reflect the device that you require and be cost effective. Another advantage is that because it is completed online, it can be built from anywhere in the world and delivered direct to your door.

Facts On DVD Copy Protection

Written by oneself on 5:34 AM

Content protection system architecture (CPSA) is a basic-level security provided by manufacturers control access to information on DVDs. IBM, Intel, Matsushita, and Toshiba (the famous DVD 4C entity) developed the technology. These companies followed the guidelines provided by the Copy Protection Technical Working Group (CPTWG) to develop encryption, watermarking, protection of analog and digital outputs.

Given below are different levels of Copy protection used DVD companies to safeguard information.

The Analog CPS (used in Macrovision Software)

Macrovision 7.0 prevents basic level analog copying of videotapes. The copy protection is often exhibited in color, distortion, rolling, black & white picture, and dark/light cycling.

Popularly known as Copyguard, this copy protection is present on Computer video cards with composite or s-video (Y/C) output.

Macrovision uses Analog protection to alter the video in two ways:

• Using Color stripe technique
• Modulating the Colorburst signal

As stated above, the protection is extremely basic and is easily overcome by small softwares like DVD Red, Video Clarifier, Image Stabilizer, Color Corrector, DVD Red, and CopyMaster. Modern DVD players can overcome the Macrovision facility with professional time-base correctors (TBCs) installed within them

The SCMS or the CGMS system

The SCMS is a serial copy generation management system that is embedded in an outgoing video signal. The protection prevents the creation of clones and master copies, which can be used to generate more copies.

A CGMS system is available in two formats:


The analog CGMS protection encrypts data on NTSC line 21. Digital camcorders and video capture cards are able detect the presence and absence of a CGMS-A


CGMS-D is used to encode information in DTCP and HDMI digital connections. Information is used on the IEEE 1394/FireWire protocol.

Content Scramble System (CSS)

The Content Scramble system is a deeper copy protection used in DVDs. Content Scramble System involves higher-level data encryption and prevents direct copying of video and DVD files. Matsushita and Toshiba created the Content Scramble System to protect the uniqueness of their DVDs.

A CSS algorithm was considered absolute offering 409 probabilities in copy protection. However, the problem ended in October 1999, when a software to overcome the CSS algorithm was posted on the Internet.

Digital Copy Protection System (DCPS)

The Digital Copy protection is the successor of the CSS system. It was used to modify digital connections between components without allowing perfect digital copies. Digital Copy protection are of two types DTCP and HDCP. Both these protections are used in Intel, Sony, Hitachi, Matsushita, and Toshiba DVD discs and Video connections.

All the offered copy protections are optional for the producer of the copy protection. The hardware versions of copy-protections are not reliable and often error prone, on the other hand, software versions are more restrictive

The Pros Of Using A Proxy To Surf The Net

Written by oneself on 4:18 AM

Proxy surfing is a technology that allows users to surf the Internet without others knowing where you have been, what you have done, or what you have seen. Proxy surfing is aimed at hiding your online identity. One of the most popular uses of proxy surfing is when the internet connection you have is protected by a firewall. Free proxy surfing is like a buffer between you and the web sites that you want to visit. Anonymous Proxy Surfing is the way to go, if you want to cover your traces.


Proxy web surfing anonymous browsing hide ip address Anonymous surfing PC Mesh Anonymous Web Surfing is an internet utility to hide your IP address while you are browsing the web. You don't need to have any knowledge of setting up proxy connections. The proxy server then contacts the Web site, and when you get the Web site's page, you don't get it directly from the site. You can buy products related to 'proxy surfing' on Amazon. In truth, proxy web surfing allows you to maintain anonymity while visiting the web pages and downloading across the internet. Because privacy, Internet crime, hacking were becoming more and more of an issue and many people were afraid to use the Internet because of the consequences, free proxy surfing sounded like a dream, something that had to be done. Nowadays more and more people are using free proxy sites to surf the net.


Free proxy surfing with the help of programs is a little more complicated and may not always work.


A traditional web proxy is not transparent to the client application, which must be configured to use the proxy (manually or with a configuration script). The Apache HTTP Server can be configured to act as a proxy server. The proxy server also builds on top of the WebSphere Application Server administration and management infrastructure, which enables the proxy to be configured as part of a WebSphere Application Server cell and administered through JMX, just as WebSphere Application Server is administered. Only rarely, in 5%, you may find problems if you use proxies that are level 3,4 or 5 and that's only if the website is configured to detectproxy server and prevent access to their site to anyone who use proxy. Proxy servers are extremely useful when configured correctly and are perfectly acceptable as long as measures are in place to ensure that only authorized users are allowed to access them.


If software was designed to insure the privacy, the anonymity of the people using the Internet, then all of these problems would find their ending. The problems that are ad-dressed and the achievements are significant. If network connections, sharing computers, router problems or other networking issues are bogging you down, then the PracticallyNetworked. Unfortunately the abuse of open proxy servers has become a common problem in the last couple of years. If an organization uses a corporate proxy and the Internet access is possible only through it, you can build a chain, being based on a type of your corporate proxy: if it is a SOCKS proxy, there is no problem, you can build any chains if it is an HTTP proxy, you can create a chain, using HTTP and CGI proxies (possible and SOCKS proxies) How to check mail in mail programs (such as Outlook) from a corporate proxy. If you are able to access other library databases via your proxy connection, or if you have successfully accessed the database via proxy before, too many users is the most likely problem.

Since the proxy server is often on the same network as the user, this is a much faster operation. In computer networks, a proxy server is a server (a computer system or an application program) which services the requests of its clients by forwarding requests to other servers. The proxy server is configured to display a "DOI Name Not Found" error page when queried for a DOI name that it cannot find. A proxy server is also commonly used as a firewall. A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services. For the purpose of this document, the term proxy server is narrowed in scope to refer only to proxy servers between web browsers and web servers.

Do you recognize the 7 warning signs of a weak password?

Written by oneself on 3:52 AM

by Michael Paul

When's the last time you really thought about how you create passwords to access all that good stuff on your computer? Yesterday? Last week?


Your personal passwords are the keys to accessing information you stored on your PC or online accounts. Creating safe passwords is important to prevent malicious users from stealing this information and using your name and account to open credit cards, apply for mortgage, or steal your identity for online transactions.

In most cases, these identity theft attacks may occur without you knowing it, until it becomes too late. To prevent this from happening, create strong passwords and keep them well protected.

The trouble with creating strong passwords is that most folks don't have a really clear idea of what a strong password really is. While it's not always easy to spot a strong password, weak passwords are extremely easy to point out.

And just because your password is strong for you, doesn't mean it will be strong for someone else. Keep the following items in mind when you are creating your passwords. If your chosen super secret code has any of the following attributes, chances are you're not picking a very strong password. Scratch that, rewind, and try again.

The following are the top 7 signs of a weak password, in no particular order:

Short passwords. The shorter a password is, the easier it can be for a hacker to figure it out. I know that having a short password makes it easy for you to remember, but it also makes it easy for everyone else. Avoid short passwords. An average password should be at least eight or more characters.

No character combinations. OK, so it's easier for you to just use letters or numbers. Have you ever thought about using any of those symbols on your keyboard? You should

No character variations. Remember those characters we just talked about? If you use fewer kinds of characters in your password, the longer it should be. A 20-character password made up of random numbers and letters is about 35,000 times stronger than a 10-character password made up of a combination of letters, numbers and symbols.

No use of the good ol' shift key. If you press down the "shift" key, a variety of symbols can be added to your password to make it stronger. These symbols can include punctuation marks or any symbols that are unique to your language.

Lots of repeated characters. Sure, you can have your password be "44444444". Your friendly neighborhood identity thief will thank you. Passwords such as "4444", "1234, "qwerty", or any adjacent letters on the keyboard do not make your passwords secure.

Look-alike substitutions. You thought you were so slick by using a "0" for "o" or even "$" for "s". Not hardly. Malicious users who may possibly crack your passwords cannot be fooled by look-alike replacements. However, if you wish to include look-alike substitutions, strengthen your passwords by adding case variations, misspellings and character length.

Your name is your login name. Avoid using any part of your name, social security number or birthday. These kinds of data are the first things criminals will try to guess.

Here's one of the top keys that you can use to avoid those weak passwords and keep the bad guys out. In developing a strong password, think of a sentence that you will not forget, such as "my daughter is three feet tall". If your password system support phrases, use your sentence as a password and add spaces between each character. Conversely, if the system cannot recognize phrases or sentences, convert the sentence into a password, such as "mditft" or "mdi3ft".

After creating a strong password, always remember your passwords by heart or write them down. Contrary to popular belief, writing down passwords is not that dangerous - as long as you keep them safe from others.

How To Remove Unwanted Startup Programs As Fast As Possible

Written by oneself on 5:07 AM

By: Manu Geol

You have complete control over the programs that startup when you turn on your computer. Removing unwanted programs from startup will boost the startup speed.

This is how to check what programs are running on startup and removing unwanted ones: (It is very easy)

1) Click Start

2) Click Run

3) Type msconfig

4) Wait for a window to popup.

5) Click on Startup tab

6) Un tick the boxes next to the items you do not want to load on startup. Please make sure you know what you are doing. If something is not familiar with you do not untick it. Certain programs need to start on startup for windows to function properly.
Untick what you are sure you do not want. Example: MSN messenger.

7) Once done hit OK.

When you install new programs like Nero Scout for example, which is a backup utility. This software automatically loads itself on startup. When this happens follow the steps above to untick it. I also had same experience with Trillian (a messenger software) and many more.
What I open automatically on startup are NoAdware, Avast antivirus, and Comodo Firewall software. Those are important for security purposes.You can also remove most software from running at startup by visiting their settings. Take for example NoAdware or Avast. By opening software and going to settings, there is an option that allows you to enable or disable run at windows startup.

This technique works on all versions of windows, as long as you have start button you can do it. If not simple open the software that is running on startup. Then go to its settings to disable it on startup.

That gives your startup speed a boost.

Discover the steps to take to remove programs from starting on windows startup. How to boost your startup speed. Different methods to remove startup programs explained.

Fix Blue Screen of Death Error

Written by oneself on 5:00 AM

By Sherman Choo

For non techy people that need a solution because they have a "Blue Screen Error" crash that happens whenever you do the following:

1) Loading Microsoft Applications

2) Playing Games

3) Using a Tally software

4) You moved your mouse

This error that you have is the Blue Screen of Death aka BSOD, where the computer screen turns blue, and asks if you have installed any new hardware or software and informs that you need to reboot your computer to fix this error. Here are a few things that can help you fix the blue screen error.

1)Registry Cleaner software

I prefer to use software and fix any errors before deciding what else to do. Reason for this is that going into hardware is little difficult. Opening up the case, changing ram etc. Sometimes when we install multiple programs or delete programs, this can cause the computer to run very slow. The software runs a scan on your harddisk and clears out errors that are giving your problems.

2) Change the Ram Changing Ram is little inconvenient. You'll need to check it the rams at fault. If its a DIY computer and you have 2 sticks of RAM, remove one and see if the problem comes back. Or download Ram checking software to test if the ram is faulty. If you're using Dell or HP, they should have tech support and their own software inbuilt to test the RAM functionality. So just call them for help.

3) In rare cases, both the above don't solve the Blue Screen problem, then the problem could like with the power supply.

If that's the case, then you'll need to backup important data into a thumbdrive and send your PC for repair. The Blue Screen error will not go away on its own and it will come back to haunt you when you did not save that Microsoft Excel File you had spent 2 hrs working on.

Get Rid Of Computer Viruses In 3 Easy Steps

Written by oneself on 7:24 AM

By Ian Gloman

The Computer. To some, it is the greatest invention in modern history, to others, it's their worst enemy. You do not have to be one of those people. You do not have to turn on your computer to error messages, frozen screens, and even lost files. Those days are a thing of the past. You can easily get rid of computer viruses 3 easy steps.

Step 1 - Scan Your Computer

You've probably already figured out you have a virus, whether it's by the frozen screen, constant error logs, or the missing files, it's pretty obvious. Now it's time to figure out WHAT virus you have. This is the easiest part. There are 100's of virus scanning and removing products on the internet today, some are even 1000's of dollars. Luckily, there are many websites that offer programs for under $50, but work much better than the overpriced options. Below are a few examples:

RegSWEEP - RegSweep is the latest in PC error diagnostic and repair. RegSweep can do a complete scan of your entire file system and registry in under 2 minutes! All corrupt files, paths, and registry keys will be analyzed and automatically repaired so that your PC functions just as when you first purchased it, Guaranteed.

Registry Fix - This software will inform you of where the errors exist, and what potential errors they might cause. Registryfix will scan for errors related to ActiveX controls, DLL issues, Windows explorer errors, Windows installer issues, Internet Explorer errors, Iexpore and System32 errors, Runtime errors, Outlook and Outlook Express Errors, EXE errors, Svchost errors and a wide variety of other system issues.

Netcom3 - Netcom3 Internet Security Software speeds up your computer, detects and removes spyware and adware, Viruses, Trojans, Dialers, Worms and a host of other dangerous parasites.

These are three of the best programs on the internet. I have used all of them, and had great success. All of them allow instant downloads, and they even allow free virus scans. I do recommend buying the software, as it will come in handy if viruses return.

Now scanning your computer is easy. All programs basically run the same. You open the program (probably through a shortcut on your Desktop), then find the "Scan PC, Scan Files, Scan Now, etc." button. Click that button, and it should begin. Some programs take over an hour to finish scanning, others can be done in minutes. When it is finished, depending on the program you chose, it should have all your corrupted files and their locations compiled into a list. Now it's time to get rid of them.

Step 2 - Removing The Virus

Many viruses are temporary internet files you've managed to pick up while surfing the web. All these files are stored in the same folder, something along the lines of C:\WINDOWS\Temp. These corrupted files are disposable. So in your program, select that file off your list, then find and click the delete button, and it's gone. Deleting a virus is that simple. The key here is to NOT delete important infected files, as your computer will crash beyond repair. So it is very important to identify where the corrupted file is, what the corrupted file is, and what it's function was. So take some time and look at the file's path, and make sure it is not in the "Program Files" folder, and if it is, make sure it is not related to a program you use frequently. Another folder you won't want to delete files from is your "System 32" folder. If the program your bought has a "Clean File" button, or something along those lines, always use that first. This way you don't have to risk deleting something important. If you can avoid deleting important files, you should be able to clean your computer without wrecking it.

Step 3 - Keeping Your Computer Virus-Free

Now that you've cleaned your computer, it's important to maintain it. This can be done by regularly scanning your computer. I try to scan my computer weekly, sometimes even more than that. This is simply because I have many valuable files on my computer I would never want to lose. I always recommend buying AT LEAST one anti-virus software, they always come in handy. If you maintain your computer's health, you too will begin to look at your computer as a piece of art.

You May Think That Your Home Computer Network Is As Safe As Bug In A Rug - It Is Not

Written by oneself on 4:21 AM

You may think that your home computer internet network is as safe as a “bug in a rug”. After all your Linksys or D-Link brand or another popular brand offers state of the art security features. Perhaps you have the standard WEP 64, or the “safe as the banks “WEP 128 encryption format. Perhaps you have even gone one step further to the ultra newer safe WPA router data security formats or even to greater security heights.

Your computer network is ultra secure. Or so you think and have beer reassured. Perhaps you have even had a “computer security professional “do the setup and maintenance,

And yet your personal data or banking information may be stolen. Your children may be directed to “bad “internet sites or worse. Your windows security updates may be compromised leaving your computer and network open to wide and wider scale attacks on your computer. Your confidential passwords – whether they are for email, medical, airline or even banking may be compromised or stolen. Finally your computer may be utilized as a “zombie” in large scale denial of service attacks on the internet. Your computer and many thousands of other may be set, waiting patiently for long periods of time, to be activated as a sleeper agent. Which along with many thousand of other remote computers are set on secret activation to altogether overwhelm some target whether it be government computers, the CNN online news network or whatever?

How are all of these threats possible? Computer security is always a case of cat and mouse with human ingenuity always at the root of the game. The hackers do this,
The computer security network react to fix the security hole it issue – whether it be Microsoft, Apple Computer or the Computer Hardware of Computer Hardware accessories manufacturers . And then the computer hackers think of an alternate means of attack.

In this case, even though it apparently seems that even though your wireless or simple cabled non wireless computer network has another gaping security hole. Home routers are at risk of being compromised by remote hackers. As a result of innocently or inadvertently visiting web pages malicious standard java script type software can access the controls of your home router and reset the controls inside the router to cause you big trouble.

Your router can be set to visit certain sites instead of where you wish to go. This may be simply to redirect you to sites containing advertising of the villain’s daily choice. You may be taken inadvertently to websites which in a flash download further viscous and mean software, on a regular basis. Or even worse you may be taken to fake sites which are not what they represent. For example you may well type in the bank of America bankofamerica.com website. You may even have searched the name by Google. You will think you are being directed to this banking website where you enter your account name and password only to discover you cannot access your account because you are a bogus copy of the front page of that website whose purpose is to steal your banking account and passwords.

The answer to this security problem is simple. Simply change the administration password in your router from the default out of the box, out of the manual and factory to anything else.

As a result the malicious java script will not be able to unlock and enter your router and do its damage. The simple answer to these router security issues and securing your router firmly is to easily and simply change the administration password on your router – whether it is wireless or a wired router. Now your home computer network and router will be safe from this threat.

BIOS Beep Codes

Written by oneself on 8:33 AM

What is a BIOS Beep Code?

When you power on a computer the BIOS immediately takes control of the computer and performs the P.O.S.T (Power On Self Test). At the end of the POST the computer will play an audible 'BEEP' through either the PC's internal speaker of through speakers attached to the sound card (if you have a built-in sound chip). If the POST completed successfully without detecting any problems with then system will play a single short beep to let you know the test is complete and the computer will continue to startup and load the operating system.

If during the POST the BIOS detects a problem it will normally display a visual error message on the monitor explaining what the problem is. However, if a problem is detected before the BIOS initializes the video card, or a video card is not present or not detected then the BIOS will play several 'BEEPS' through the speaker to let you know there is a problem. Depending on the type of the BIOS you have the BIOS may play beeps in a specific pattern to indicate what the problem is, or play the same beep a number of times indicating the problem. It is very important that you pay close attention to the number and/or pattern of the beeps your computer plays on startup.

Below is a table of the most common AMI, Phoenix and Award BIOS beep codes.


  • 1 Beep - Memory Refresh Failure (check memory)
  • 2 Beeps - Memory Parity Error in first 64KB block (check memory)
  • 3 Beeps - Memory Read/Write Error in first 64KB block (check memory)
  • 4 Beeps - Motherboard timer not functioning (possible motherboard replacement)
  • 5 Beeps - Processor Error (may need replacement Processor)
  • 6 Beeps - Gate A20/keyboard controller failure (possible motherboard replacement)
  • 7 Beeps - Processor Exception Interrupt Error (may need replacement Processor)
  • 8 Beeps - Display Memory Read/Write Failure (reseat or replace video card)
  • 9 Beeps - ROM checksum Error (replace BIOS chip or motherboard)
  • 10 Beeps - CMOS shutdown Read/Write error (possible motherboard replacement)
  • 11 Beeps - Bad Cache Memory - test failed (replace cache memory)


Phoenix BIOS beep codes are a series of beeps separated by a pause, for example:
beep --- beep beep --- beep --- beep beep would be 1-2-1-2
  • 1-1-4-1 - Cache Error (level 2)
  • 1-2-2-3 - BIOS ROM Checksum
  • 1-3-1-1 - DRAM Refresh Test
  • 1-3-1-3 - Keyboard controller test
  • 1-3-4-1 - RAM Failure on address line xxxx (check memory)
  • 1-3-4-3 - RAM Failure on data bits xxxx of low byte of memory bus
  • 1-4-1-1 - RAM Failure on data bits xxxx of high byte of memory bus
  • 2-1-2-3 - ROM copyright notice
  • 2-2-3-1 - Test for unexpected interrupts


There are 2 main beep codes for the Award BIOS:
  • one long beep and two short beeps - Video error (reseat or replace video card)
  • two short beeps - Non-Fatal Error (reseat RAM, check other components)

More on BIOS beep codes or numeric codes see the manufacturer's website:

Nvidia Gaphic Card Geforce 8800GTX Review

Written by oneself on 6:01 AM

By Kirk Jensen

If you want the fastest graphic card on the planet then buy the Nvidia graphic card Geforce 8800 series, if you want the fastest gaming system on the plant then buy the two Nvidia Geforce 8800GTX graphic cards and put them together using the SLI.

The Geforce 8000 series has a new chip, 90 nanometre, with over 680 million transistors, it is considered to be the largest graphics chip ever built. The fastest 8000 version is clocked at 575 MHz while the GTX version clocks at 500 MHz.

The Geforce 8800 series graphic cards are the first to use the Direct 10 chip. "It is also the first to support the 'unified' marchitecture." It uses the same "pipeline calculates vertex, pixel and geometry Shader information".

"Geforce 8800 GTX has a core working at 575MHz. GDDR 3 memory works in a rather odd 384-bit mode and it has twelve chips, totally of 768MB of memory. While we all expected 1024 would be the next step, Nvidia decided to go for 768MB due its different memory controller. Nvidia clocked the memory at 1800MHz with a totally bandwidth of respectable 86.4 GB/s and a fill rate of 36.8 billion a second."

The Geforce 8000 series unified parallel Shader is designed to support 128 individual stream processors running at 1.35GHz in terms of speed. The speed numbers came from Nvidia. Because it support direct x 10 it will only work with Window Vista operating systems.

This card is hot, literally it has two power 6 pin connectors means that the card gets 2x75 watts from the cables plus an additional 75 watts from the PCIe bus. This brings total power consumption to an amazing 225 Watts.

The Nvidia graphic card Geforce 8800 GTX "has a dual slot cooler - massive and heavy but it does the job. The card always worked around 55Celsius in 2D mode and a bit higher in 3D."

The test of two cards

The first card tested was the EVGA Geforce 8800 GTX with a brand-new ACS3 Cooler. "The ACS3 cooler is actually more efficient that Nvidia's reference cooler as the card works at 55C in 2D mode while the Nvidia reference cooler cools the card to 60 Celsius only. This is what makes the difference between EVGA card and the rest of the cards based on the reference cooler design." The box the card come in is super small.

Second card was a Leadtek Geforce 8800 GTX card with the SLI or Scalable Link Interface for linking two graphic cards together. The Leadtek card supports HDCP or High-bandwidth Digital Content Protection and the driver CD also includes Vista drivers.

The driver for both card has a couple of new features, One new featured includes support for 16X Anisotropic filtering. The big news is that Nvidia finally supports FSAA 8X and 16X. Nvidia's Luminex is a marketing name for incredible image quality that includes support for 16X Anti-alasing, 128-bit HDR (High Density Resolution) and support for 2560x1600 resolution with a high frame rate.

Bench marketing The cards where tested using the following:
"Foxconn C51XE M2aa Nforce 590 SLI motherboard
Sapphire AM2RD580 with SB600 board for Crossfire
Athlon FX 62 2800 MHz 90 nanometre Windsor core
2x1024 MB DDR2 Corsair CM2X1024-6400C3 memory
Seagate Barracuda 7200.9 500GB SATA NCQ hard drive
Thermaltake Mini Typhoon Athlon 64/X2/FX cooler and Intel CPU's
OCZ 700W GameXstream power supply"

The two nvidia graphic card where test on the 3Dmark03 a "single EVGA G80 card, EVGA eGeforce 8800GTX ACS3 575/1800MHz scores 30485. it is just slightly faster than the 7950 GX2 card, 2500 slower than Crossfire and more than 10000 faster than a single fastest X1950XTX card."

When the EVGA-Leadtek 8800GTX SLI 2x 575/1800MHz combo scores 49390, almost 50K a perfect score for the 3Dmark03. With the SLI it is sixty two percent faster than a single card. A single Geforce 8000 graphic card is fifty four percent faster than an X1950XTX. With the Vertex Shader test the Geforce 8000 graphic card is twice as fast as the ATI's faster card.

"Nvidia Graphic card EVGA eGeforce 8800GTX ACS3 575/1800MHz scores is eighty four percent faster than the ATI's X1950XTX in Shader model 2.0 test and seventy one in Shader model 3.0 / HDR testing."

List of computer video games used in the test
"Doom 3 scores around 135 FPS at first three resolutions and drop to 125 at the 20x15, SLI even then scores 135 so this is clearly CPU limited. EVGA eGeforce 8800GTX ACS3 575 / 1800 MHz is almost 80 percent faster at 2048x1536. Doom 3 with effects on scores 130 FPS at first two resolutions and later starts to drop but is still faster than 7950 GX2 cards all the time. SLI doesn’t drop at all at first three resolutions only slightly drops at 20x15.

FEAR scores are up to sky with the weakest score of 95 FPS at 20x15, faster than Crossfire in the last two resolutions and from GX2 and X1950XTX at all times. It is up to 66 percent faster than X1950XTX and 68 percent from the Gainward 7950 GX2 card. SLI is again 68 percent faster than Crossfire a massive difference.

Quake 4 runs up to forty seven frames faster on G80 and SLI gets the score better but not much. G80 is always faster than GX2 and Crossfire. Quake 4 with FSAA and Aniso runs some forty percent faster than ATI's fastest card and 30 per cent in Crossfire versus SLI G80.

Far Cry with effects on performance is matched with both G80 and X1950XTX while the SLI can outperform both in 20x15.

Serious Sam 2 is faster on ATI in first two resolutins by three frames while EVGA eGeforce 8800GTX ACS3 575 / 1800 MHz wins by eight, or fifteen frames at higher resolutions. SLI is 23 per cent faster than a single G80 and 43 percent faster than X1950xTX.

Serious Sam 2 with FSAA and Aniso on always scores faster at EVGA eGeforce 8800GTX ACS3 575 / 1800 MHz card but not that much, some nine to ten percent while the SLI is 54 per cent faster than a single card and sixty eight percent than ATI's card."

In Short
The Nvidia Geforce 8000 series graphic cards are amazing beating out the latest ATI card in virtually every test. The card is pricey, expect to pay around $600 or more for one of them. It is a very long card and it does get hot but the card can be consider the fastest graphics card on the market right now, it is also very stable as well.

Stating from the beginning if you want the fastest graphic card on the planet then buy the Nvidia graphic card Geforce 8800 series, if you want the fastest gaming system on the plant then buy the two Nvidia Geforce 8800GTX graphic cards and put them together using the SLI.
