Written by oneself on 7:44 AM

By: Angel Solutions

If you need something for preventing the unscheduled downtime or data loss when there is a sudden loss of power then there is a UPS (Uninterruptible Power Supply) which is an inexpensive way to protect your computer hardware and files from unexpected power loss.Uninterruptible power supply is not enough for this operation. Software, hardware and configuration etc. all together establish a UPS system in order to recover from power fluctuations or unexpected power loss that can damage your system.
But how can you select the right Uninterruptible power supply for your system?

Following are the steps to choose Uninterruptible power supply:

Step 1: If your budget is limited then select a standby or "��off-line"�� UPS that switches to battery power when the power fails.

Step 2: If you require an unlimited backup power then select an "on-line" UPS.

Step 3: If your need lies between the two other types then choose a "line-interactive" UPS.

Step 4: Find out the requirements of the total power needs of equipment in terms of watts and volt-amperes that you will connect to the UPS

Step 5: Select an uninterruptible power supply that exceeds or equals the total power needs of the equipment that you will connect to it

Step 6: Don't forget to compare the following specifications and these are:
1.surge suppression (in joules - more is good)
2.maximum surge current (in amps - more is good)
3.battery recharge time (faster is good)
4.suppression response time (faster is good)
5.number of AC outlets (more is good)

Step 7: Find out the unit under consideration containing a replaceable battery which is user-replaceable.

Step 8: Compare battery operating times.

Step 9: Look for LEDs or alarms that show wiring issues, whether the battery is low and whether the equipment is running on UPS battery.

Step 10: Check for a unit with electromagnetic interference, modem surge protection and radio-frequency interference noise deduction if you require those features

Step 11: If you buy a more expensive unit the you will get it with software that automatically closes applications, saves documents and turns off equipment when power fails.

Step 12: Compare insurance guarantees as well as warranties

Unbiased review of the new iPhone 4

Written by oneself on 6:40 AM

by christopher ciprian

It's acknowledged. Consumer Reports' technicians have just completed testing the iPhone 4, and have confirmed that there is a shortcoming with its signal. When your finger or hand comes in contact with a spot on the phone's lower left side-a very easy thing, more so even for lefties-the signal can severely degrade enough to cause you to lose your connection altogether if you're in an area with a weak signal. Due to this problem, we can't recommend the iPhone 4.We induced this outcome after testing all three of our iPhone 4s (purchased at three separate distributers in the New York area) in the controlled environment of CU's radio frequency (RF) isolation chamber. In this room, which is impervious to outside radio signals, our test technicians plugged in the phones to our base-station emulator, a apparatus that simulates carrier cell towers (see video: IPhone 4 Design Defect Confirmed). We also tested several other AT&T phones the same way, including the iPhone 3G S and the Palm Pre. None of those phones had the signal-loss mishaps of the iPhone 4.

Our outcomes call into question the recent claim by Apple that the iPhone 4's signal-strength issues were generally an optical illusion resulted by insufficient software that "incorrectly displays 2 more bars than it should for a given signal strength."

The tests also indicate that AT&T's reception might not be the primary suspect in the iPhone 4's much-communicated signal woes.

We did, however, find an within your pocketbook strategy for suffering iPhone 4 users: Cover the antenna gap with a piece of duct tape or another thick, non-conductive material. It may not be lovely, but it works. We also expect that using a case would do away with the symptoms. We'll investigate a few cases this week and report back.

The reception fault is a primary reason that we did not cite the iPhone 4 as a "advisable" model, even though its evaluation in our other tests mounted it atop the latest Product reviews of smart phones that were produced today.

The iPhone evaluated high, to a degree because it sports the most sought display and best video camera we've ever found on any smartphone, and even dominates its high-scoring competitors with more suitable battery life and such modern day features as a front-facing camera for video chats and a built-in gyroscope that turns the phone into a super-responsive game controller. But Apple essentially needs to develop a permanent-and free-fix for the antenna issue before we can encourage the iPhone 4. click here

A Pocket Pc Is Portability At It's Best

Written by oneself on 5:51 AM

by thebanneradblueprint

A Pocket PC is a handheld computer, which features many of the same capabilities as a modern PC. These handy little devices allow individuals to retrieve and store e-mail messages, create a contact file, coordinate appointments, surf the internet, exchange text messages and more.Every product that is labeled as a Pocket PC must be accompanied with specific software to operate the unit and must feature a touchscreen and touchpad. Pocket PC products are created by some of the world's top computer manufacturers, including HP, Toshiba and Gateway. As is the case with any new technology product, the cost of a Pocket PC was substantial during it's early release. For approximately $700.00, consumers could purchase one of top-of-the-line Pocket PCs in 2003. These days, customers are finding that prices have become much more reasonable now that the newness is wearing off. For approximately $350.00, a new Pocket PC can now be purchased.

Even years after their release, Pocket PCs are a staple in the world of travelers, college students and business leaders. The need to stay in constant communication with family and/or colleagues has kept the portability factor one that remains popular today. When traveling for business or other reason, individuals often need a way to stay in touch. A desktop computer is simply not a feasible accompaniment and notebooks are at a constant risk for being stolen or damaged. A Pocket PC can obviously fit inside of a pocket, but may also find a safe haven in a purse, duffle bag, tote or other small compartment.

Purchasing a Pocket PC can be a difficult choice because of the various models and manufacturers available. When considering the options, consumers must look at any available warranty, included software and capabilities. Much like in the world of traditional desktop and notebook computers, manufacturers are always looking for a way to outdo the competition and the customer often finds that such actions may lead to a real bargain.

Like any other computer, a Pocket PC must be cared for in such a way that it is not exposed to extreme heat or cold for prolonged periods of time, is not shuffled around carelessly and is carefully packed for safety during travel. Owning a Pocket PC means having access to an address book, your e-mail account, the world wide web and your appointment calendar all in the comfort of your own pocket. Carrying the internet in your pocket? Now that is portability at it's best.

An upcoming legend or a legendary disappointment? - the apple iPad

Written by oneself on 5:28 AM

by Daniel O.

There were many rumors the last half year about a tablet PC apple was going to announce. Like before at almost every big Apple release or announcement like a new iPod or the iPhone, the internet was flooded by "top secret" information about features and reports on Apples purchases of component parts etc. The new product has been hyped long before its release. And at the day of the official announcement Apple always matched the high expectation, except this time.

When Steve Jobs presented their new baby, the iPad, everyone waited for the unexpected feature Jobs would name soon. But there was no super stunning feature. Though the iPad seemed cool, it was not the revolutionary tablet PC everybody was waiting for.

One of the reasons for this is, that the OS of the tablet will be a pimped iPhone OS, not a adjusted version of Mac OS Snow Leopard as hoped by many potential customers. The iPad seems to be just a really big iPhone or iPod touch. Another critic point is that Apples new mini computer won't support Flash. Apple don't like to support Flash, because they think it's an outdated format and caused many errors on the OS. Especially with the slowly upcoming HTML 5 which is meant to replace flash, Apple had a reason to ignore it. While many customers are upset about Apple's ignorance on flash, others are more than happy with this decision. The dependency of a lot of content in the internet just from a privet company like Adobe isn't a good solution, so some people see Apples's politics as a chance to make Flash dispensable.

Additionally criticized points for the iPad are the leak of multitasking for most applications (the ability to open several programs at the same time), a missing cam for video chat and the fact that only software from the App Store will run on the iPad. People expected a equivalent to all the netbooks out there, just with Apple's and Jobs' touch, but got something else. Apple didn't try to make a better netbook with touchscreen, they are going to offer a whole new product. The iPad was a disappointment for those who expected a real mini computer like a windows or mac PC. If you look at the iPad from a neutral perspective it's not that bad at all. The iPad is a product that's made for a market which grew just in the last years. It's a simple gate to the portable internet, to information and fun everywhere. And that's what it's meant to be, the iPad is made to offer people an easy access to the internet. If you have to look up something quickly, if you're sitting on the couch and like to surf or if you just want to read newspaper articles or ebooks, the iPad is a great solution. Especially the last feature mentioned above is something Apple tries to improve with their tablet computer. The New York Times already announced an application to offer paid content you normally only get with their printed media. Apple also tries to beat Amazon's popular ebook-reader Kindle. So you have to think about all this and for what reason you like to have an iPad to be clear if it's something for you. But one thing is for sure, the iPad will sell as almost all Apple products do. At least the hype and the design will contribute enough to make this true.
