Some Concepts Related with Operating Systems

Resource allocation is the process of assigning computer resources to certain programs for their use.

Multiprocessing means that a computer with more than one central processing unit can run multiple programs simultaneously, each using its own processor.

Multiprogramming is running two or more programs in the same time frame, concurrently, on the same computer.

Time-sharing is a special case of multiprogramming in which several people use one computer at the same time. Each user is given a time slice in which the computer works on that user's tasks before moving on to another user's tasks.

Response time is the time between the user's typed computer request and the computer's reply.

Memory management is the process of allocating memory to programs and of keeping the programs in memory separate from each other. Some systems divide memory into separate areas, sometimes called partitions or regions, each of which can hold a program.

In the virtual storage (or virtual memory) technique of memory management, part of the application program is stored on disk and is brought into memory only when needed for execution. Memory is considered real storage; the secondary storage holding the rest of the program is considered virtual storage.

Paging divides a program into equal-size pieces (pages) that fit exactly into corresponding noncontiguous memory spaces (page frames). The operating system keeps track of page locations using a page table.
