memory management
     
         A collection of techniques for
        providing sufficient memory to one or more processes in a
        computer system, especially when the system does not have
        enough memory to satisfy all processes' requirements
        simultaneously.  Techniques include {swapping}, {paging} and
        {virtual memory}.  Memory management is usually performed
        mostly by a {hardware} {memory management unit}.
