Computer And The Graphics Cards

Many people and businesses today own computers; however, very few people know what components make up the computer and how they all work together. There are some computer components that people do recognize by name and graphics cards are just one of them. Graphics cards have been heard of but what are they exactly and what role do they play in the makeup of a computer? These supplemental cards are components that translate binary data into images. The cards break down an image and decide where pixels belong in order to create the image on the screen. Amazingly the cards can store multiple different pictures, break down multiple different pictures while displaying a totally different picture on screen. The supplemental cards are made up of a bunch of memory and a fast processing unit. These supplemental cards are not essential for a computer system and most people do not need high end graphics cards for everyday computer needs. Today most motherboards have some sort of integrated graphics but for the ultimate graphics experience a supplemental card is a definite must. How do you know which graphics cards are good? It is actually easier than you think. Finding a good card is fairly simple because they will generally be visually appealing. A top of the line card is going to have lots of memory and a fast processor. Some even have illustrations, fans or heat sinkers. A graphics card is not a necessary component for a good computer because a lot of motherboards come with built in graphics. A supplemental card allows for better, crisper, clearer images. The people who work with graphic images and are gaming enthusiast are the ones that really need the additional card capabilities. The top of the line cards are more than anyone could possibly ever need for graphics capabilities. A middle of the line card is usually sufficient for gaming and graphic imaging. A supplemental graphic card is not needed for anyone that is just using the computer for email or typing because the motherboards integrated graphics will suffice for this type of computing. Graphics cards may sound like they are a needed component but depending on what you are using the computer for will determine how important it really is. There are many different cards on the market today and they range from top of the line to mid-grade. Most computing can use the mid line cards for complete graphics abundance. Just be sure that your cards have optimum memory and a fast processor to get the most for your graphic needs.

Tips to Prevent Outlook Express Messages from Disappearing

Outlook Express DBX file structure is prone to corruption for various causes. This is the reason why you often observe email messages disappearing from OE folders. The most significant reasons causing this issue are antivirus software scanning and background compaction. Ironical but true, if an antivirus software is configured to scan Outlook Express message store, this can trigger corruption. Also, the background compaction feature of Windows prior to Windows XP SP2 can corrupt the folders. So, the best practice is to turn off these features and hence, prevent any Outlook Express Recovery solution requirement while folder corruption. Turn Off Antivirus Software Scanning An antivirus software can corrupt the message store or a folder when attempting to delete any message that contains a potential virus. This also applies to anti-spamware applications that somehow interrupt with the working of Outlook Express. Thus, you should disable email scanning using an antivirus software. Viruses usually come as email attachment. Thus, even though you disable the antivirus scanning for incoming or outgoing emails, you are still protected. This is because when you try to open a virus infected attachment, the software will detect it and will warn you against it. Turn Off Background Compaction To remove the wasted space that generates whenever you delete or move a message file, Outlook Express comes with a default enabled feature called background compaction. Whenever the application is left idle for some time, it starts compacting the folders. The process slows down your system and consumes 100% of CPU resources. But it can result into folder or store compaction, if interrupted. You can disable the feature under Tools | Options| Maintenance option of 'background compaction' and compact the folder whenever required manually. Windows XP SP2 removes this feature, though not completely. It now starts compacting the folder when you open and close Outlook Express 100 times. At 100th time, you will be prompted to compact the folders. Outlook Express Folder Corruption Emails unexpectedly disappearing from OE folders is the usual indication of .dbx file corruption. To repair them, you should use DBX Repair software. Since no built-in repair utility is available for repairing the OE folders, Outlook Express Recovery software are the only solutions that you can use to repair. Stellar Phoenix Outlook Express Recovery is a powerful utility with rich graphic features that repairs and restores corrupted .dbx files. It is a comprehensive repair product for corrupted .dbx files. This Outlook Express Recovery utility is compatible with Outlook Express 5.x and 6.x. The software recovers all email messages without modifying the original content and view.

What's That File? File Extensions Intro
Author: kimberly valerio
In an effort to be "user-friendly," Windows (and perhaps some other operating systems) hides the most important part of a file name from new computer users: the extension. Okay - we're assuming that the reasoning behind hiding extensions is a "user-friendly" one because we just can't come up with any other reason for hiding them. No harm could ever come from seeing an extension, but plenty could be learned from it. Fortunately you have this article to guide you through some of the most common extensions that you'll run into. But before you can see file extensions, you need to turn them on. From Windows Explorer, click on the "Tools" menu, and select "File Options." Click the "View" tab and then uncheck the box next to "Hide file extensions for known file types." Click "OK" and you'll notice that the files in Windows Explorer show a dot and group of three letters after their names. That dot and group of three letters is known as an "extension," and the extension explains what kind of file it is. A file could be a plain text file, an image, a sound, a video, or program. But without seeing the extension, you wouldn't know it unless you double-clicked on it. The following list defines some of the most common extensions that you'll find on your computer. .au - This extension indicates a sound file. Most sound players will load up and play this kind of file. .art - This extension indicates an image file that was compressed with AOL (America Online) technology. Both Internet Explorer and the AOL service software can display this kind of file, however if you don't have AOL installed on your system, Internet Explorer will display it. .avi - This extension indicates a video file playable by most multimedia viewers including Microsoft's Media Player. .bmp - This extension indicates another image file that might have originated from Windows Paint program. .dll - This extension indicates a Dynamic Link Library which may contain additional programming code for software. Many different programs often share Dynamic Link Libraries and you'll find a bunch of them in the Windows/System directory (but don't ever delete them)! .exe - This extension indicates a program or an application like Microsoft Word, Internet Explorer, or Outlook Express. Use extreme caution when downloading .exe files from the Internet since malicious programmers like to hide viruses in these types of files. .gif - This extension indicates another image file and it stands for "Graphics Interchange Format." .Gif files are often smaller than .bmp files (described earlier) and they're commonly found on Internet web pages. .jpg - This extension indicates yet another image file and it stands for "Joint Photographers Experts Group." Like the .gif file, it's commonly found on Internet web pages, however it's much smaller than both the .gif image and the .bmp image. .mid - This extension indicates a sound file created with a Musical Instrument Digital Interface. Windows Media Player will open and run these files, however they don't sound like normal .wav or .mp3 files (described later). .Mid files are designed to product synthetic sounds using a computer's sound card. .mp3 - This extension indicates a sound file that authentically reproduces voice and/or music. Windows Media Player will open and run this kind of file. .scr - This extension indicates a screen saver file. .sit - This extension indicates a Macintosh archive StuffIt file. They will not open on a Windows system without a special utility. .ttf - This extension indicates a font especially designed for use on a Windows system. It stands for "True Type Font." .txt - This extension indicates a plain text file that can be opened with Notepad. .wav - This extension indicates a sound file that like the .mp3 file, can be opened with Windows Media Player or Windows Sound Recorder. .Wav files are much larger than .mp3 files. .zip - This extension indicates a Windows archive WinZip file. They will not open on a Macintosh system without a special utility.
