Detailed explanation-1: -Only core parts of the operating system kernel bypass this address translation and use real memory addresses directly. Virtual memory is always being used, even when the memory that is required by all running processes does not exceed the volume of RAM that is installed on the system.
Detailed explanation-2: -Virtual memory enables data that is in RAM and not currently being used to be transferred to the hard disk. This frees up room in RAM for other programs and data. When the data on the hard disk is needed again, any other unused data is transferred to the hard disk before the original data is transferred back to RAM.
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: -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.
