Operating System (OS) Interview Questions And Answers - Part I.



1. What Is An Operating System?

An operating system is the most important software that runs on a computer. An operating system is a program that acts as an intermediary between the user and the computer hardware. It manages the computer's memory, processes, and all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer's "language". Without an operating system, a computer is useless.

The purpose of an OS is to provide a convenient environment in which user can execute programs in a convenient and efficient manner.


2. What Are The Basic Functions Of Operating Systems?

Functions of an operating system are:
  • Shield the user from the intricate low-level details and provide an easier to program and more powerful interface to the machine or network => virtual machine.
  • Manage the system resources: Protection, Scheduling, Sharing, File system, Accounting, etc. This function is obviously important for multitasking (OS2) and multi-using/multitasking (UNIX, VMS) operating systems. Even for single-user/single task, resource management is important (e.g. file system allocation and structure).
