An operating system is a system software, that after being initially loaded into the computer by a good program, manages all the other programs in a computer.

The application programs make use of the operating system by making request for services through a different Application Program Interface (API). In addition, users can interact directly with operating systems through a user interface such as command language or Graphical User Interface(GUI).


Functions Performed by the OS :


♤ The operating system acts as an interface between the computer hardware and the user.

♤ It manages computer's memory.

♤ It handles interrupts.

♤ It schedules the jobs.

♤ It manages Input/Output devices.
