What is operating system?

An operating system (O.S) is an interface between a computer user and computer hardware. O.S is a system software which performs all the basic tasks like file management, memory management, process management, handling inputs/outputs and controls all the peripheral devices such as monitor, keyboard, scanner, printers.

 Let us take an example of human body, if we consider human body as a computer hardware then  the operating system can be defined as soul of it.

Examples of some popular operating systems:- Windows, IOS, Linux, Android, and many more.
