Virtual Memory in Operating System:

  • A computer can address more memory than the amount physically installed on the system. This extra memory is actually called virtual memory and it is a section of a hard disk that's set up to emulate the computer's RAM.
  • Virtual memory implements the translation of a program's address space to physical addresses.
  • Virtual memory serves two purposes. First, it allows us to extend the use of physical memory by using the disk.
  • Second, it allows us to have memory protection because each virtual address is translated into a physical address.
