Operating System:

A program that is initially loaded into the computer memory and manages all the other programs and resources of a computer is called Operating system.

  • The operating system manages the applications and the hardware, such as disk drive, memory, and peripheral devices.
  • The users interact with the operating system by using the command language or shell, and the graphical user interface.
  • An application makes the service request by the application programming interface to use the operating system.
  • Operating system performs different type of services
    • Determining the running application and its order
    • Time allotment to each application
