_________ is a memory management technique used by operating systems to expand available RAM by transferring data to secondary storage.

  • Cache Memory
  • RAM
  • ROM
  • Virtual Memory
Virtual memory is a technique used by operating systems to extend available memory by storing data temporarily on disk storage. When RAM is full, less frequently accessed data is moved from RAM to a space on the hard drive called the swap file or paging file. This frees up RAM for other processes, allowing the system to run more programs simultaneously.
