Memory Management:
It is the procedure of controlling and coordinating computer memory, assigning portions called blocks to several running programs to optimize performance of total system. Memory management exists in hardware, in the OS (operating system), and in programs and applications.
In hardware, memory management includes components that physically store data, such like memory caches, RAM (random access memory) chips, and flash-based SSDs (solid-state drives). In the Operating System, memory management involves the allocation (and constant reallocation) of particular memory blocks to specific programs as user demands for modify. At the application level, memory management makes sure the availability of sufficient memory for the objects and data structures of each running program at all times. Application memory management joins two associated tasks, called as recycling and allocation.
While the program requests a block of memory, a portion of the memory manager called the allocator assigns that block to the program.
While a program no longer needs the data in earlier allocated memory blocks, those blocks become obtainable for reassignment. This task can be manually done (by the programmer) or automatically (by the memory manager).

Purpose of memory management:
The reason of the memory management system is to load programs into memory in such a manner as to give each program loaded the memory that it needs for execution.
In multiprogramming operating system there are various programs residing in the memory simultaneously in the memory. The memory management system has three primary tasks. It attempts to carry out these tasks in a way that is fair and capable to the programs that must be loaded and executed.
1. It keeps track of which parts of the memory are being used currently and by which process into memory together with the space being utilized and also keeps track of available space.
2. It maintains one or more queues of programs waiting to be loaded into memory as space becomes accessible, based on such program criteria as priority and memory requirements.
3. While space is available, it allocates memory to the programs that are next to be loaded. It also de-allocates a program's memory space while it completes execution.
The de-allocated space is made available for other programs.
