What is virtual memory on a computer?

1 Answer

Answer :

answer:Virtual memory is space on the hard drive that your computer uses a a direct extension of the RAM. If a program has been sitting on the RAM for a while and isn’t doing anything, then it is copied to the hard drive into this ‘virtual memory’ for fast recovery, without uselessly taking up RAM. (if this was too technical, then I can go into more detail) To fix it I need to know what operating system you are running, how much RAM you have, and how many programs you are trying to run at once.
