  • Meaning of Operating System

Every computer must have an Operating System in order to run other programs. It is sometimes called O/S. When you switch on or press the computer power button, it first loads the O/S during the booting process. It checks all the components attached to the computer and more often than not, it displays an error message if there is a problem.

What is an Operating System?

An operating system, therefore, is the system software (program) that manages all of the software and hardware on the computer.

When you are using your computer there are usually different computer programs running at the same time, and they all need to access your computer’s central processing unit (CPU), memory, and storage.

The operating system is responsible for coordinating these activities and making sure each program gets what it needs.

It takes control after the computer is started. It determines the type of command that may be used on the system. It is usually supplied by the computer manufacturer or his agent (computer vendor)

System software can come in the form of operating systems, translators, and utility programs depending on what they are meant for.
