FUNDAMENTALS OF COMPUTER

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: -The area of the hard drive used for virtual memory is called a swap file.

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: -Virtual memory also allows the sharing of files and memory by multiple processes, with several benefits: System libraries can be shared by mapping them into the virtual address space of more than one process. Processes can also share virtual memory by mapping the same block of memory to more than one process.

Detailed explanation-5: -Virtual memory is a method that computers use to manage storage space to keep systems running quickly and efficiently. Using the technique, operating systems can transfer data between different types of storage, such as random access memory (RAM), also known as main memory, and hard drive or solid-state disk storage.
