Operating system is the midway between hardware and other system and application programs which is closely related to hardware and provides an interface for users to work with. One of the major objective of an OS(Operating System) is to maximize the resource utilization of the system. That is all available resources like CPU time, memory and I/O are effectively and concurrently utilized to achieve maximum efficiency. OS manages these resources and allocates them to various programs running according to the priority of requests it receive.
We can not provide a complete and adequate definition for an operating system. It is certain concepts and characteristics that define it. One closely definition is "An Operating system is a program that is running on a hardware assembly every time it is working which provides everything necessary to make the system usable."
