| A
program that controls a device. Drivers act as an interface
between the operating system and the devices that make up
a computer to enable all the components to understand each
other and work together. In the case of a graphics card,
the driver informs the operating system of the different
screen resolutions it supports (number of colours, frequency
of updates, resolution, etc.) Although operating systems
already include controllers for the most commonly used peripherals
on the market, the manufacturers modify them from time to
time to improve their performance. |
