Cards in this deck (5)
- 1What is a device driver?A device driver is a piece of software that controls the hardware and importantly provides an interface so that programs can use the device.
- 2Why are drivers needed?Drivers are needed to allow the OS to control hardware. Without drivers, the computer would not be able to send and receive data correctly to hardware devices, such as a printer. Each operating system needs its own driver for the same hardware device.
