Operating system:

  • The most important program that runs on a computer is operating system.
  • Operating System (OS) is a collection of software that enables the computer resources to have communication with computer system.
  • OS is used to control traffic in a computer, it schedules time for processing and allocates memory for each process.
  • Operating system acts as an interface between user and computer.
  • There are many other types of operating system such as Windows, Macintosh, LINUX, UNIX, and mobile operating systems such as android OS, and iOS, and so on
  • Basic operations of OS are as follows:
    • Getting input from the keyboard
    • Displaying output in the monitor
    • Monitoring the files.
  • OS control the peripheral devices such as printers, hard drives, and mouse.
  • The responsibilities of OS are bound to get higher when it comes to security, because it provides the access rights for users.
