computer
     
         A machine that can be programmed to manipulate
        symbols.  Computers can perform complex and repetitive
        procedures quickly, precisely and reliably and can quickly
        store and retrieve large amounts of data.
     
        The physical components from which a computer is constructed
        (electronic circuits and input/output devices) are known as
        "{hardware}".  Most computers have four types of hardware
        component: CPU, input, output and memory.  The CPU ({central
        processing unit}) executes programs ("{software}") which tell
        the computer what to do.  Input and output (I/O) devices allow
        the computer to communicate with the user and the outside
        world.  There are several kinds of memory - fast, expensive,
        short term memory (e.g. {RAM}) to hold intermediate results,
        and slower, cheaper, long-term memory (e.g. {magnetic disk} and
        {magnetic tape}) to hold programs and data between jobs.
     
        See also {analogue computer}.
