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: -Random Access Memory RAM is used to hold the data the CPU needs while it runs a program, which saves it time to reach the secondary storage every time it needs a piece of data or instruction. However, RAM is also one of the most expensive components of a computer device, with its cost often measured per gigabyte.

Detailed explanation-3: -Virtual memory provides virtual address mapping between applications and hardware memory. It provides many functions, including multitasking (multiple tasks executing at once on one CPU), allowing multiple processes to access the same shared library in memory, swapping, and other functions.

Detailed explanation-4: -The main difference between physical and virtual memory is that the physical memory refers to the actual RAM of the system attached to the motherboard, but the virtual memory is a memory management technique that allows the users to execute programs larger than the actual physical memory.

Detailed explanation-5: -Paging. Paging is a virtual memory technique that separates memory into sections called paging files. Segmenting. Segmentation is another method of managing virtual memory. 12-Dec-2022
