Fragmentation is caused when an operating system breaks a file into pieces because there is not enough space on the storage device where the file was originally saved.
One example of this would be where a file was originally saved, then modified causing the file to be larger in physical space than first anticipated, the operating system will then break the file into 2 or more pieces and store them in different parts of the storage area. The system would then keep a record of where the different parts of the file are stored, this is achieved through the use of a File Allocation Table (FAT) or similar file system such as the
NTFS used under Windows NT and Windows XP operating systems. Then, when the operating system requires the file again, it will query the file system FAT, NTFS or other) to find out where the different parts of the file are located on the partition/drive. Defragmentation is the term given to the process of scanning the file system and rejoining the split files back into consecutive pieces. The process of defragmenting can be time consuming, but it is one of the easiest ways to increase the performance of your PC, the frequency of which a PC should be defragmented will directly depend on the amount of usage


DIMM (Dual Inline Memory Module) is a RAM memory module with mounted memory chips; DIMMs have a 64bit data path and are widely used in PCs with 64bit processors. The dual inline part refers to the way the chips are mounted on the module. Typically there are two common types of DIMM PC100 and PC133, further they come in either 144 pin or 168 pin packages, 144 pin normally used in laptops and 168 used in the standard PC

A device driver is a program that is written specifically to control a certain piece of hardware such as a soundcard, modem graphics card, printer, scanner etc. The driver allows the hardware to act seamlessly with the operating system, the computer motherboard and other devices. Each manufacturer supplies drivers for their specific products; these drivers are often updated with time so it is a good idea to keep your drivers current. To find specific drivers for any of your devices it is best to start at the manufacturer's website as they normally have updated drivers in their respective support pages


A DVD (Digital Video Disc) drive is designed to read DVD discs, CD-ROM data discs and CD audio discs. A DVD disc although similar in looks as a CD, is a much different animal. It does use optical technology to store the data like a CD, but the tracks are much closer than the ones on a CD. Also there are basically two types of DVD discs a single layer and a dual layer disc. The single layer DVD's can hold up to 4.7 Gigabytes of data or 7 times that of a CD and the dual layer can hold 9.4 gigabytes of data or 14 times that of a CD


DVD-/+R (Digital Video Disc-Recordable) refers to a recordable DVD disc. There are two formats of DVD recordables DVD-R and DVD+R. Both formats hold the same amount of data (4.7 Gig or 9.4 Gig). However, home DVD players generally only play one format or the other. The disks are different and therefore they are not interchangeable. Newer DVD writers will read and write both formats. If your desire is to create DVDs to play on your home DVD player be sure which type you player is compatible with. Also some DVD players will not play DVDs created on a computer no matter which format. If you're considering buying a new DVD player this might be something to research before you buy
