Operating system as resource manager: · A computer system usually has many hardware and software resources such as processor , memory, disk printer, I/O devices etc. · The task of resources management becomes essential in multi-user operating system where different user compute for the same resource. Operating system manages resources in two ways : 1. Time multiplexing : it defines the sharing of resources on the basis of fixed time slices. For example, the operating system allocate the resources, such as CPUto program A for fixed time slice. 2. Space timing: it defines the concurrent sharing of resources among different programs.for example, sharing of hard disk and main memory is space multiplexing.
