From The Collaborative International Dictionary of English v.0.48 :

  Infinity \In*fin"i*ty\, n.; pl. Infinities. [L. infinitas;
     pref. in- not + finis boundary, limit, end: cf. F.
     infinit['e]. See Finite.]
     [1913 Webster]
     1. Unlimited extent of time, space, or quantity; eternity;
        boundlessness; immensity. --Sir T. More.
        [1913 Webster]
  
              There can not be more infinities than one; for one
              of them would limit the other.        --Sir W.
                                                    Raleigh.
        [1913 Webster]
  
     2. Unlimited capacity, energy, excellence, or knowledge; as,
        the infinity of God and his perfections. --Hooker.
        [1913 Webster]
  
     3. Endless or indefinite number; great multitude; as an
        infinity of beauties. --Broome.

     4. (Math.) A quantity greater than any assignable quantity of
        the same kind.
        [1913 Webster]
  
     Note: Mathematically considered, infinity is always a limit
           of a variable quantity, resulting from a particular
           supposition made upon the varying element which enters
           it. --Davies & Peck (Math. Dict.).
           [1913 Webster]
  
     5. (Geom.) That part of a line, or of a plane, or of space,
        which is infinitely distant. In modern geometry, parallel
        lines or planes are sometimes treated as lines or planes
        meeting at infinity.
        [1913 Webster]
  
     Circle at infinity, an imaginary circle at infinity,
        through which, in geometry of three dimensions, every
        sphere is imagined to pass.
  
     Circular points at infinity. See under Circular.
        [1913 Webster]

From The Jargon File (version 4.4.7, 29 Dec 2003) :

  infinity
   n.
  
      1. The largest value that can be represented in a particular type of
      variable (register, memory location, data type, whatever).
  
      2. minus infinity: The smallest such value, not necessarily or even usually
      the simple negation of plus infinity. In N-bit twos-complement arithmetic,
      infinity is 2^N-1 - 1 but minus infinity is - (2^N-1), not -(2^N-1 - 1).
      Note also that this is different from time T equals minus infinity, which
      is closer to a mathematician's usage of infinity.
  

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

  infinity
  
     1.  The size of something infinite.
  
     Using the word in the context of sets is sloppy, since
     different infinite sets aren't necessarily the same size
     cardinality as each other.
  
     See also aleph 0
  
     2.  The largest value that can be represented in
     a particular type of variable ({register, memory location,
     data type, whatever).
  
     See also minus infinity.
