Question

memory management within an operating system

Answer 1

Memory Management is the process of coordinating and controlling the memory in a computer, Blocks are assigning portions that are assigned to various running programs in order to optimize the overall performance of the system. This technique helps in keeping the track of each and every memory location, whether the memory location is allocated to some process or it is free.

This technique decides which process will get memory at what time. It also keeps the count of how much memory can be allocated to a process. As it keeps the tracks of everything so whenever some memory gets freed or unallocated it updates the status correspondingly.
