Detailed explanation-1: -Virtual memory is a common technique used in a computer’s operating system (OS). Virtual memory uses both hardware and software to enable a computer to compensate for physical memory shortages, temporarily transferring data from random access memory (RAM) to disk storage.
Detailed explanation-2: -Virtual memory is a feature of an operating system that uses hardware and software to compensate for shortages of physical memory. It transfers pages of data from random access memory (RAM) to disk storage.
Detailed explanation-3: -Virtual memory is temporary memory. The size of the virtual memory storage depends on the addressing scheme used by an OS and the available secondary memory. The main advantage of virtual memory is that an OS can load programs larger than its physical memory.
Detailed explanation-4: -A computer can address more memory than the amount physically installed on the system. This extra memory is actually called virtual memory and it is a section of a hard disk that’s set up to emulate the computer’s RAM. The main visible advantage of this scheme is that programs can be larger than physical memory.
Detailed explanation-5: -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.
