Detailed explanation-1: -Virtual memory is an area of a computer system’s secondary memory storage space, such as an HDD or SSD, that acts as if it were a part of the system’s RAM or primary memory. Ideally, the data needed to run applications is stored in RAM, where the CPU can quickly access it.
Detailed explanation-2: -Where is the data stored when it is in virtual memory? It is stored on an area of a secondary storage device e.g. hard disk drive. Describe how a computer uses virtual memory. A process running on the computer may need to store data in the physical memory.
Detailed explanation-3: -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-4: -Hard Drives The hard drive is the secondary storage standard in modern computing. Many computers bundle hard drives as internal storage mediums, and today hard drives can include spinning disks and solid-state drives (SSDs).
Detailed explanation-5: -The operating system has a special program called the virtual memory manager; it breaks each application into chunks and loads them into virtual memory, putting some parts into RAM and the rest in a special file on the hard drive.
