Virtual memory is a computer storage technique that allows a computer to store more data than can actually fit in its physical memory. This is done by using a portion of the computer’s hard disk drive as a temporary storage space. When the computer needs to access data that is stored in virtual memory, it is copied from the hard disk drive into physical memory. This process is transparent to the user, and it allows the computer to run programs that are larger than its physical memory.
There are a number of benefits to using virtual memory. First, it allows computers to run programs that are larger than their physical memory. This can be important for running complex applications, such as video editing software or 3D games. Second, virtual memory can help to improve the performance of computers that are running multiple programs at the same time. This is because the computer can store frequently used data in virtual memory, which reduces the amount of time that the computer spends accessing the hard disk drive.
