An Operating System is a program (a set of instructions) that gets loaded into a computer when it is first turned on.It manages all of the other applications on the computer (like word processors, games, web browsers, etc.), and lets them (and the user) interact with each other and with the computer's hardware (the hard disks, keyboard, monitor, printer, etc.)
(MSDOS, Windows and MacOS are other examples of Operating Systems.)
