COMPUTER FUNDAMENTALS

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: -On a PC, RAM is the physical memory is where operating system data, running programs and open documents are held. When RAM runs low, virtual memory can move data from the RAM to a space called a paging file. This process allows for RAM to be freed up so that a computer can complete the task.

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: -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-5: -This process is known as swapping . Using virtual memory makes a computer run slower, as the processor has to wait while data is swapped between hard disk and RAM.
