  Computer \Com*put"er\ (k[o^]m*p[=u]t"[~e]r), n.
     1. One who computes.
  
     2. (Computers) an electronic device for performing
        calculations automatically. It consists of a clock to
        provide voltage pulses to synchronize the operations of
        the devices within the computer, a central processing
        unit, where the arithmetical and logical operations are
        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
           operator. Different types of computer are variously
           called analog computer, number cruncher,
           number-cruncher, digital computer, and pari-mutuel
           machine, totalizer, totaliser, totalizator,
           totalisator.
  
     Syn: data processor, electronic computer, information
          processing system.

     3. (Computers) same as digital computer.

From The Collaborative International Dictionary of English v.0.48 :

  digital computer \digital computer\ n.
     1. (Computers) a computer that represents information by
        numerical digits with a fixed number of values; -- most
        commonly each piece of information is internally
        represented in binary code, as an array of bits, which
        are information units each of which can take only two
        values. The possible values of each bit are
        conventionally represented as the numbers 1 or 0.
  
     Note: The bits of information are usually further organized,
           maniplulated, and discussed as nybbles (4 bits,
           rarely used), bytes (8 bits, most commonly used), or
           words (from 16 to 128 bits, and in the future
           probably more). A word is usually defined as the
           number of bits that are processed at one time by the
           central procesor unit.
  
     Syn: .

From WordNet (r) 3.0 (2006) :

  digital computer
      n 1: a computer that represents information by numerical
           (binary) digits

From The Free On-line Dictionary of Computing (18 March 2015) :

  digital computer
  
      A computer that represents numbers and other data
     using discrete internal states, in contrast to the
     continuously varying quantities used in an analog computer.
  
     Some of the fundamental ideas behind the digital computer were
     proposed by Alan Turing between 1936 and 1938.  The design
     of the Atanasoff-Berry Computer (1937-1942) included some of
     the important implementation details but the first digital
     computer to successfully run real programs was the Z3
     (1941).  ENIAC (1943-1946) was the first electronic digital
     computer but was only programmable by manual rewiring or
     switches.
