<title>What is a driver?</title>

Devices are the physical “parts” of your computer. They may be

external like printers and monitor or internal like graphics

and audio cards.

In order for your computer to be able to use these devices, it needs to know

how to communicate with them. This is done by a piece of software called a

device driver.

When you attach a device to your computer, you must have the correct driver

installed for that device to work. For example, if you plug in a printer but

the correct driver is not available, you will not be able to use the printer.

Normally, each model of device uses a driver that is not compatible with any

other model.

On Linux, the drivers for most devices are installed by default, so

everything should work when you plug it in. However, the drivers may need to be

installed manually or may not be available at all. 

In addition, some existing drivers are incomplete or partially

non-functional. For example, you might find that your printer cannot do

double-sided printing, but is otherwise completely functional.
