Introduction to Operating System


An operating system is the interface between the user and the computer hardware. It implements a virtual machine that is easier to program than bare hardware.

Functions of Operating System

The operating system is designed to function for the following purposes:

  • It controls allocating and using the computing system’s resources among the various users and tasks.
  • It provides an interface between the computer hardware and the programmer that simplifies and makes coding, creating, and debugging of application programs feasible.

Examples of Operating Systems

Some of the examples of operating systems are as follows:

  • Windows 
  • Linux
  • MacOS
  • Android
  • iOS

Benefits of Operating System

Operating system benefits are as follows:

  • Convenience: An OS makes a computer more convenient to use.
  • Efficiency: An OS allows the computer system resources to be used efficiently.
  • Ability to evolve: An OS should be constructed in such a way as to permit the effective development, testing, and introduction of new system functions without interfacing with service.
