Detailed explanation-1: -A system using virtual memory uses a section of the hard drive to emulate RAM. With virtual memory, a system can load larger or multiple programs running at the same time, enabling each one to operate as if it has more space, without having to purchase more RAM.
Detailed explanation-2: -Virtual memory (also known as a page file) is essentially a block of space on your hard drive or solid state drive allocated by the OS to pretend to be RAM when your physical RAM runs short for actively running programs.
Detailed explanation-3: -Only core parts of the operating system kernel bypass this address translation and use real memory addresses directly. Virtual memory is always being used, even when the memory that is required by all running processes does not exceed the volume of RAM that is installed on the system.
Detailed explanation-4: -Virtual memory is a built-in component of most modern desktop computers. It’s part of a computer’s CPU and is a more cost-effective method for managing memory than expanding its physical memory storage system.
