(a) Device drivers
(b) Interrupt handler
(c) both (a) and (b)
(d) None of these​

Answer 1

1. The lowest level of input output control consist of

ans. (C) both (a) and (b)

Answer 2

" Option C) Both (a) and (b) ".

Explanation:

The lowest level of input output control consist of device drivers and interrupt handler.

Input/output control is another name for order release, which controls a manufacturing system's input. Input output control also refers to a specific order release mechanism. that keeps the input to a shop equal to the output during a given time period.

This systems are used in management to obtain an effective output and improve the efficiency of the production department by using input/output control system.

Here,

A device driver or driver is a set of files that says a piece of hardware how to function by communicating with a computer's operating system.

A device driver is a program, that lets the operating system (OS) communicate with specific computer hardware.

The work of the interrupt handler is to service the device and stop it from interrupting process. Once the handler returns, the CPU resumes what it was doing before the interrupt occurred.
