Which of the following are functions of an operating system?

1.Checking spellings in a document

2.Managing the processes that run on the system

3.Providing a user interface to the user

A1 & 2 only

B1 & 3 only

C2 & 3 only ✓ Correct

D1, 2 & 3

Correct answer: (C) 2 & 3 only

Explanation

An operating system manages the processes running on the system, which is Statement 2.

It also provides a user interface so the user can interact with the machine, as in Statement 3.

Statement 1 is wrong because checking spellings is a task of a word processor, not the operating system.

Managing processes covers scheduling, starting and stopping the programs in memory.

The user interface may be graphical or command-line, but either way the system supplies it.

An operating system also handles memory, files and connected hardware in the background.
