Driver (computer)
From the Simple English Wikipedia, the free encyclopedia that anyone can change
A driver is a program that lets the operating system communicate with the computer hardware.
Computer parts need a driver because they do not use standard commands. (Ex.: ATI and NVIDIA graphic cards do the same jobs, but not the same way). Different operating systems also need different drivers, a driver written for Linux can not be used by Microsoft Windows.
Many parts of a computer need drivers, but the most popular are:
- Graphic card
- Modem
- Network card
- Sound card
Some other parts do not need drivers because they use a kind of standard; the operating system recognizes those parts and knows how to use those parts.
(not complete list)
- Processor
- CD and DVD drive (including player and burner); however, for SCSI drives the controller card's driver may be needed as well.

[change] Compatibility Issues
Using the wrong device driver can prevent hardware from operating correctly. For example, a HP printer will not work with a computer that only has an Canon driver. Keeping drivers up-to-date avoids problems when using new programs (such as Windows Vista) with the piece of hardware.
