Detailed explanation-1: -Fragmentation. As processes are loaded and removed from memory, the free memory space is broken into little pieces. It happens after sometimes that processes cannot be allocated to memory blocks considering their small size and memory blocks remains unused. This problem is known as Fragmentation.
Detailed explanation-2: -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-3: -To accommodate the allocation process, the OS continuously moves processes between memory and storage devices (hard disk or SSD), while tracking each memory location and its allocation status. The OS also determines which processes will get memory resources and when those resources will be allocated.
