Detailed explanation-1: -A swap file is a space set aside on the hard drive to be used as the virtual memory extension for the computer’s RAM. When the swap file is needed, it is sent back to RAM using a process called page swapping. This system ensures the computer’s OS and applications do not run out of real memory.
Detailed explanation-2: -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.
