From The Collaborative International Dictionary of English v.0.48 :

  Zero \Ze"ro\, n.; pl. Zerosor Zeroes. [F. z['e]ro, from Ar.
     [,c]afrun, [,c]ifrun, empty, a cipher. Cf. Cipher.]
     [1913 Webster]
     1. (Arith.) A cipher; nothing; naught.
        [1913 Webster]
  
     2. The point from which the graduation of a scale, as of a
        thermometer, commences.
        [1913 Webster]
  
     Note: Zero in the Centigrade, or Celsius thermometer, and in
           the R['e]aumur thermometer, is at the point at which
           water congeals. The zero of the Fahrenheit thermometer
           is fixed at the point at which the mercury stands when
           immersed in a mixture of snow and common salt. In
           Wedgwood's pyrometer, the zero corresponds with
           1077[deg] on the Fahrenheit scale. See Illust. of
           Thermometer.
           [1913 Webster]
  
     3. Fig.: The lowest point; the point of exhaustion; as, his
        patience had nearly reached zero.
        [1913 Webster]
  
     Absolute zero. See under Absolute.
  
     Zero method (Physics), a method of comparing, or measuring,
        forces, electric currents, etc., by so opposing them that
        the pointer of an indicating apparatus, or the needle of a
        galvanometer, remains at, or is brought to, zero, as
        contrasted with methods in which the deflection is
        observed directly; -- called also null method.
  
     Zero point, the point indicating zero, or the commencement
        of a scale or reckoning.
        [1913 Webster]
        [1913 Webster]

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

  zero
   vt.
  
      1. To set to 0. Usually said of small pieces of data, such as bits or words
      (esp. in the construction zero out).
  
      2. To erase; to discard all data from. Said of disks and directories, where
      ?zeroing? need not involve actually writing zeroes throughout the area
      being zeroed. One may speak of something being logically zeroed rather than
      being physically zeroed. See scribble.

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

  zero
  0
  
     1.  0, ASCI character 48.  Numeric zero, as
     opposed to the letter "O" (the 15th letter of the English
     alphabet).  In their unmodified forms they look a lot alike,
     and various kluges invented to make them visually distinct
     have compounded the confusion.
  
     If your zero is centre-dotted and letter-O is not, or if
     letter-O looks almost rectangular but zero looks more like an
     American football stood on end (or the reverse), you're
     probably looking at a modern character display (though the
     dotted zero seems to have originated as an option on IBM
     3270 controllers).  If your zero is slashed but letter-O is
     not, you're probably looking at an old-style ASCII graphic
     set descended from the default typewheel on the venerable
     ASR-33 Teletype (Scandinavians, for whom slashed-O is a
     letter, curse this arrangement).
  
     If letter-O has a slash across it and the zero does not, your
     display is tuned for a very old convention used at IBM and a
     few other early mainframe makers (Scandinavians curse *this*
     arrangement even more, because it means two of their letters
     Burroughs/{Unisys">collide).  Some Burroughs/{Unisys equipment displays a zero
     with a *reversed* slash.  And yet another convention common on
     early line printers left zero unornamented but added a tail
     or hook to the letter-O so that it resembled an inverted Q or
     cursive capital letter-O.
