Virtual memory is a computer system’s capability to compensate for the lack of physical memory (RAM) by temporarily transferring data from RAM to disk storage. This process is known as paging. When the computer needs to access the data, it is paged back into RAM. Virtual memory can improve the performance of a computer system by allowing it to run more programs and processes than would otherwise be possible.
There are several benefits to using virtual memory. First, it can improve the performance of a computer system by allowing it to run more programs and processes than would otherwise be possible. Second, it can help to prevent the system from crashing by providing a buffer for data that would otherwise be lost if the system ran out of RAM. Third, it can help to extend the life of the computer’s hardware by reducing the amount of wear and tear on the RAM.
