A driver is a piece of software that the computer operating system needs to understand how to operate an attached device. The driver is very important because it also acts like a translator between the device and all programs that use the device. Every device attached to the computer including keyboard, mouse, printer, webcam,  and scanner needs a driver. Drivers are important to properly functioning equipment.

Drivers can sometimes become corrupted. Sometimes new drivers are needed to update the functioning of attached equipment.  If you are having trouble with any peripheral device, surf over to the website of the manufacturer and see if there are new drivers available for your device. The website will give you instructions for installing a new driver if there is one available.
