Choosing & Installing A New Operating System

Written by oneself on 7:27 AM

by Victor Epand

If you buy a computer, one of the aspects which many people bear in mind very seriously as an influencing factor is the operating system installed. The operating system is the collection of software utilities which allows you to use a computer. Common operating systems include Microsoft Windows, Mac OS and Linux.

However, this really doesn't have to be such a significant factor, since it may often prove preferable to choose your operating system independently from the computer system itself. Granted, this isn't always possible since, for example, it wouldn't prove to be possible to run Microsoft Window on an Apple Mac, nor the Mac OS on an IBM compatible PC.

But each of these operating systems has been released many times, with many different versions. Often the newer versions have unreported or unresolved bugs in it, and may not be compatible with all of the software you have been using. For this reason, many people can be put off buying a new computer because of the operating system. Conversely, some people choose a computer as a direct result of the operating system bundled with it.

Of course, no computer manufacturer gives away the operating system for free, unless the operating system happens to be Linux, which is free anyway. The price of the operating system will be absorbed into the overall retail price for the computer system. But buying a computer system without an operating system can give you much greater choice.

This might put off many people, and it may well not be suitable for the beginner. But in reality it is not at all hard to install a new operating system. In most cases it is no more difficult than inserting a disk, rebooting the computer and following the simple on screen instructions.

Even if your computer comes with an operating system pre installed, you don't have to keep it. Instead, you can easily buy your preferred operating system, and replace the old one with your preferred choice.

If you do decide to replace your operating system, always make sure that you have backed up all of your important data, as this will often mean that any data on your computer will be lost. In some cases it is possible install two, or even more, different operating systems on one computer. This will mean that when you switch on your computer, you'll be asked which OS you wish to use. This means that it is almost like having several computers in one, and gives you the chance to experiment with other operating systems before finally committing to the one you feel best.

Many people these days use a version of Linux. There are many reasons for this, one of which is the fact that it is usually free, or at least, only a very small price. Linux is a community driven operating system, written by volunteers and interested fans around the world. This can mean that the system is very personalised, thoroughly tested, constantly being updated, and offering many of the features which the very same users have requested or find useful.

The BlackBerry Curve Review

Written by oneself on 9:39 AM

by David Parish

The Blackberry Curve offers several new features that can make this phone a great investment. If you like thin mobile phones you will like the Blackberry Curve. But don't be fooled by the thin design, it features a large screen so you won't find your self struggling to read your messages. The Blackberry Curve is still one of the larger mobile phones in overall size compared to the simple smaller packages of the newer mobile phones today.

The Blackberry Curve is one of the latest Blackberry with a trackball located in the center of the phone. We found that the trackball can be is great to help you navigate through your menu selections. This is by far the better way to navigate compared to the older models. The trackball is as easy as using a mouse.

The Blackberry Curve features a 2.0 megapixel camera so you can take a wonderful picture every time. You can also play videos and music from your Blackberry Curve. This feature is built into the mobile phone allowing you to access your music and videos whenever you can.

One of the best features of the Blackberry Curve is the keyboard. Most consumers purchase the Blackberry Curve because it is ideal for messaging and typing with ease. The keypad featured on the Blackberry Curve is large enough to see and type without accidentally hitting other buttons while sending a text. Although the keyboard is protected by a plastic cover they can still withstand the constant typing and pressing of the keys.

The processor built into the Blackberry Curve is a 312 MHz Intel processor. This is the same type of processor that is found in other Blackberry. Keep in mind that this 312 MHz may not sound like a lot but in a small device, such as a mobile phone, it is enough. So you shouldn't have anything to worry about when uploading and downloading.

The screen is 320 x 240 pixel in LCD. The size of the screen is 2.4 inches. This large screen is great for watching your videos and viewing photos from your photo album. You can also read files and enjoy text messaging because you are able to see it.

Memory is no problem for the Blackberry Curve. With a 64 MB of flash memory built in you will be able to store without worries. Although it may be a hassle, you can find the memory card slot by removing the battery. Use a memory card to store ample songs, videos, photos, and more.

We like music, do you? If you like your music on the go you can use your Blackberry Curve as a digital portable player. The Blackberry Curve includes a built in speaker so you can listen to your music anytime you want. When purchasing a Blackberry Curve, a set of earphones are included in the package for quiet listening.

Over all the Blackberry Curve is an excellent choice for anyone who may be in business for themselves or anyone who works. It may not be so convenient for the younger generation as it doesn't have everything easily accessible that a teen would want.

Reliable iPhone 3G 2.2.1 Unlock

Written by oneself on 4:36 AM

By: Gen Wright

There seems to be a lot of debate when it comes to the matter of unlocking or jail-breaking iPhones. Lots of people feel that there is some strict law in place and that by purchasing a new iPhone you are promising to be a consistent AT&T customer. This is simply. The truth is that you purchased the product, this means you are the owner, and you can use it in whichever way you whish. With that being said, often times - especially using software Unlock methods, your warranty that has been provided by Apple will become null and void once you complete the unlocking process, so you must ensure that you unlock your phone in a safe and reliable manner.

When it comes to unlocking your 3G iPhone 2.2.1 there are some techniques and tricks that you need to be aware of in order to complete the whole process. The last thing that you want to do is end up with an expensive decoration rather than a phone that can be used to its fullest. When deciding to unlock your iPhone you need to understand what you are doing and what can happen to your iPhone if not done correctly.

In the US, almost every 3G iPhone 2.2.1 will be "locked" upon purchase. The locked status will only allow the phone to work in a certain network such as AT&T for example. If you wish to use the phone with another carrier you will need to unlock the phone. The best iPhone unlocking tactics performed is using a hardware "piggy back" SIM card. Place this ultra thin SIMcard on top of the SIM from the carrier you wish to use, and your iPhone is Unlocked. You will essentially be able to use your 3G iPhone 2.2.1 in any manner that you deem fit. This piggy back sim method will never void your Apple warranty.

There are several warnings and precautions to consider when unlocking your iPhone. While you may find loads of information online such as tutorials and howto's, it is best to let an unlocking expert take care of the major details. Search for and find a reliable company that will offer your detailed step by step instructions on how to unlock your phone carefully and in a way that will not risk harm to the phone itself. By using experts such as these you will also be given the details on how to return your phone to locked status if you wish to take it in for service or use the warranty that you undoubtedly purchased along with it. Take your time, make sure you are informed and seek expert advice. Sure unlocking your 3G iPhone 2.2.1 may seem easy enough after reading some free online tips, but do you really want to risk turning your iPhone into a useless brick?

Common Myths of CPU's and GPU's

Written by oneself on 7:38 AM

By Aki Horie

So, talking about "processors and graphics cards" is a little vague. Here's a start for all of you:

1. A Few Common myths of processors and graphics cards

2. The power of processors and graphics cards

3. If one were to reign supreme and have most of the computer under its control, which one will have that control?

In this article, I will be talking about some common myths.

Common Myths of Processors and Graphics Cards

Now, many of you are new to computers, some who are pretty good with computer hardware, and there're us, the experts. But there're always common myths lurking around rising from misconceptions of a few people and spreading around through forums and websites. But I'm going to crack some of them.

One common myth I come across is this one: "A computer cannot exist without a graphics card installed." Well, most of you would probably want a graphics card installed on your computer for kicks and giggles, and maybe for shows. But that's not true; computers can run WITHOUT graphics cards. A common and one of the only options for running computers without graphics cards is to have a motherboard with integrated graphics. This is a really cool feature for those of you who don't really need the graphics power because you save money from not buying a graphics card. These motherboards with integrated graphics is definitely not as powerful as some of the mid-range and high-range graphics cards, but it will churn out more than enough power to give you a display on your monitor.

Another common myth I hear a lot is "Oh no, my Core2 processor is only 1.45 GHz, it's so slow!!!!!" Again, that's definitely NOT true. The processing speed of CPUs and its efficiency depends on many factors. One main factor is the number of cores.

As technology keeps developing and revolutionizing itself, programs and hardware must both keep up. Today, we have single-core processors, dual-core processors, tri-core processors(AMD's Phenom) and the quad-core processors. Now, if you have been "trapped" by this common myth, you will think that a 3.00 GHz Pentium processor will be faster and more efficient than a Core2 1.45Ghz processor.

Well, that's wrong; take into consideration the number of cores: the Pentium has 1, and the Core2 has two cores(in this example). Now, when you have two cores PLUS hyper-threading, this means that you essentially have 4 cores, just not written on the box or the computer. This means that you have cores just as powerful or more powerful than the one in the Pentium, and you have four of them.

As you start using more and more programs simultaneously, the Core 2 processor will have an easy time utilizing its cores, but the Pentium will have a hard time because it will only have 1 core, and it can only take on so many threads and tasks. That's why processor speeds, at first glance, do not really matter.

Delete Temporary File

Written by oneself on 9:10 AM

By George I Smith

The presence of too many temporary files is a common cause that slows down your computer by clogging a reasonable part of your hard disk drive. If you examine your hard drive, you will find several files with a tilde (~) prefix or .TMP suffix, like ~xyz.dat or xyz.tmp. Such files are called temporary (or temp) files, and you can almost always safely delete them.

The first step to delete temporary file is to defragment your hard drive after regular intervals. Defragmenting will locate the scattered pieces of these temp files, reunite them, and put them on your hard drive in orderly, contiguous cluster.

Follow the following procedure to defragment your drive:

* Click Start, Programs (in case of WinXP/Vista, it's All Programs), and then Accessories.
* Under Accessories, choose System Tools.
* After that, select Disk Defragmenter.
* Click OK after choosing the drive.

Depending on the dimension of your hard drive and the number of files on it, Disk Defragmenter can take 30 minutes to 2 hours for this job.

Another alternative to delete temporary file is to periodically erase any temp file that has been saved on your hard drive. For this, you will need to find the temp files at first. The easiest technique to do that is to make use of Windows' built-in Find utility. Click Start, Find, and then select Files Or Folders. Next, type *.tmp; ~*.* in the Named: field on the tab marked Name & Location.

With the use of this syntax, the operating system will understand that you are looking for files that begin with a tilde (~) and files that end with .TMP. After a few minutes, a list of the files will be displayed. In the display, you can click the Size column heading so that the list is sorted by file size. This will help you to view especially large temp files, if any. Remember that it is not an unusual thing to find 2MB, 3MB or even larger temp files. It is always advisable to delete any temporary file as even a small temp file will occupy space on your hard disk drive and slow down the system.

You can also use Disk Cleanup to delete temporary file. It is a built-in Windows utility that can delete such files very quickly. To utilize it, open the Start menu and then click in succession All Programs (in case of Windows 98/Me, click Programs), Accessories, System Tools and Disk Cleanup. After choosing the drive that you wish to clean, click OK. After scanning your hard drive, Disk Cleanup will show how much room it can clear by erasing particular types of files. If you are unsure what the files do, choose the entry and read the description that appears in the box below the entry. To delete selected files, click OK. However, Disk Cleanup will not delete all temporary files on your computer and unfortunately you can't instruct it to go back and perform a better job. Nevertheless, you can locate and delete most of the remaining temporary files by hand.
