What are the functions of an Operating System?

An Operating System is the core of any computer or device. It is the most important program that runs on the computer, as it is responsible for running all the other programs and applications that run in the computer.

An Operating System has three primary functions:

  • To run and ┬ámanage all the programs that are running on the system as well as allocate resources to them
  • To monitor the performance of each of the different parts, such as the central processing unit, memory, disk drives, and printers
  • To build an interface that brings the user closer to the system via the use of different modules and libraries
