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 software (program) that is responsible for the control of the hardware resources, of the computer. 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.
