performed on data, a random-access memory, where the
programs and data are stored for rapid access, devices to
input data and output results, and various other
peripheral devices of widely varied function, as well as
circuitry to support the main operations.

Note: This modern sense of computer comprises the
stored-program computers, in which multiple steps in a
calculation may be stored within the computer itself as
{instructions} in a {program}, and are then executed by
the computer without further intervention of the
