What is operating system?

What is operating system?



    Most computer users have had some experience with an operating system, but
it is difficutt to pin down precisely what an operating system is.  Part of the prob-
lem  is that  operating systems perfom, two  basically unrelated functions, and
depending on who is doing the talking, you hear mostly about one function or the
other.



    Modem computers consist of processors, memories, timers, disks, mice, network
interfaces, laser printers, and a wide variety of other devices. In the alternative
view, the job of the operating system is to provide for an orderly and controlled
allocation of the processors, memories, and I/0 devices among the various pro-
grams competing for them.
