Question

37. Which of the following provides a link between the user processes and threads and the hardware?
(A) I/O driver
(B) File system
(C) Memory
(D) LPC​

Answer 1

Option “A” is correct i.e. I/O drivers

• I/O drivers provide the link between user processes and threads and hardware.

• I/O devices are the bits of hardware used by a human (or other system) to interconnect with a computer. For example, a keyboard or mouse is an input device for a computer, whereas monitors and printers are output devices.  

• Devices for communication between computers, for example modems and network cards, characteristically perform both input and output operations.
