Which of the following are functions of an operating system?
- Checking spellings in a document
- Managing the processes that run on the system
- 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 — Managing processes and providing a user interface are OS functions, so the answer is 2 and 3.
Explanation
★Managing processes and providing a user interface are OS functions, so the answer is 2 and 3.
★An operating system manages a computer's hardware and its application programs.
★It manages the processes that run on the system, scheduling and coordinating them.
★It provides a user interface through which the user interacts with the machine.
★So items 2 and 3 are genuine operating-system functions.
★Checking spellings in a document is a feature of application software such as a word processor.
★So item 1 is not a function of the operating system itself.
