What is virtual memory?

Answer Posted / pravin

when program doesn't fit in main memory then then program is segmented and the part of program which is in currently use is kept in main memory and the remaining part of program,which is not in use is stored in secondary storage. when the executing program needs the part of program which is not in main memory then it copies that part from sec memory and replaces some program from main memory.Thus the technique which swaps the program between main memory and secondray storage is called virtual memory.
