COMPUTER FUNDAMENTALS

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 is commonly implemented by demand paging.

Detailed explanation-3: -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-4: -Answers. Technique to implement virtual memory where memory is divided into units of fixed size memory is Paging.

Detailed explanation-5: -Segmenting. Segmentation is another method of managing virtual memory. A segmentation system divides virtual memory into varying lengths and moves any segments that aren’t in use from the computer’s virtual memory space to its hard drive.
