Multiprocessing designed many supercomputers that used multiprocessing heavily. Hard drive storage commonly begins at one terabyte now and goes up to two and a half terabytes. Memory management monitors and manages the memory and knows which blocks of memory are in use, which programs are using memory, and which memory blocks are available to be used. Legislation makes it mandatory to computers through the approved facilities. It takes care of step by step processing of all operations in side the computer. Central Processing unit further includes Arithmetic logic unit and control unit, as shown in the figure:. For instance a allows the user to control the movement of the pointer a common element in user interface design.
