Detailed explanation-1: -Most of the management that occurs at the physical level is handled by the memory management unit (MMU), which controls the processor’s memory and caching operations.
Detailed explanation-2: -Paging. Paging is the memory management technique in which secondary memory is divided into fixed-size blocks called pages, and main memory is divided into fixed-size blocks called frames. The Frame has the same size as that of a Page.
Detailed explanation-3: -Worst fit: The memory manager places a process in the largest block of unallocated memory available. The idea is that this placement will create the largest hold after the allocations, thus increasing the possibility that, compared to best fit, another process can use the remaining space.
Detailed explanation-4: -Memory management is the process of allocating memory to programs and keeping the programs in memory separate from one another. Some systems divide memory into separate areas, called partitions or regions.
