Device Drivers

device driver is a program that lets the operating system communicate with specific computer hardware. Computer parts need a driver because they do not use standard commands.

Device Drivers are very essential for a computer system to work properly because without them the hardware would fail to achieve the purpose for which it was built.

How they work

Device Drivers depend upon the Operating System’s instruction to access the device and performing any particular action. An example would be a printer driver that tells the printer in which format to print after getting an instruction from the OS. Thigs like card readers, controllers, modems, network cards, sound cards, printers, video cards, USB devices, RAM, Speakers etc all require Device Drivers to operate.
