Question

What are device drivers ? Why are they important ?

Answer 1

The main purpose of device drivers is to provide abstraction by acting as a translator between a hardware device and the applications or operating systems that use it. Programmers can write higher-level application code independently of whatever specific hardware the end-user is using.

Answer 2

The Device drivers are special programs which control the

execution of a particular hardware device. Whenever we

purchase a new hardware for e.g :- a printer from the

manufacturer HP we will need to install the printer hardware

with them installation disk. This will load the new driver into the

operating system and enables us to use the hardware.Similarly

each hardware example a monitor, scanner, Mouse, keyboard,

modemetc. has its own driver. Devices from different

manufacturers need their own drivers to function properly.

Therefore it is of great importance
