  • 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 of all 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.

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