hi!
virtual memory is a technique that allows the execution of
processes that are not completely in physical memory,
and the size of program may be larger than the physical memory!
OS without this technique needs the whole program to be in
main memory to execute,other processes need to wait for the
execution of currently executing program while OS with
virtual memory technique pages are swap in memory on
demand,this on demand paging causes efficient use of system
resources.
