Memory management

Memory management is the act of managing computer memory. The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed. This is critical to any advanced computer method where over a single method might be underway at any time.[1]

Several methods have been devised that increase the effectiveness of memory management. Virtual memory systems separate the memory addresses used by a method from actual physical addresses, allowing separation of processes and increasing the effectively obtainable amount of RAM using paging or swapping to secondary storage. The quality of the virtual memory manager can have an extensive effect on overall method performance.
