COMPUTER FUNDAMENTALS

Detailed explanation-1: -However, users should not overly rely on virtual memory, since it is considerably slower than RAM. If the OS has to swap data between virtual memory and RAM too often, the computer will begin to slow down–this is called thrashing.

Detailed explanation-2: -How does virtual memory work? Virtual memory uses both the computer’s software and hardware to work. It transfers processes between the computer’s RAM and hard disk by copying any files from the computer’s RAM that aren’t currently in use and moving them to the hard disk.

Detailed explanation-3: -Virtual memory can be slow and inefficient, and this can cause applications to run more slowly than they would without it. This is because virtual memory requires the computer to access the hard drive, which is much slower than accessing RAM.

Detailed explanation-4: -Windows sets the initial virtual memory paging file equal to the amount of installed RAM. The paging file is a minimum of 1.5 times and a maximum of three times your physical RAM. You can calculate your paging file size using the following system.
