       more than four spatial dimensions, and have various modes
       of vibration. Considering particles as strings avoids
       some of the problems of treating particles as points, and
       allows a unified treatment of gravity along with the
       other three forces (electromagnetism, the weak force, and
       the strong force) in a manner consistent with quantum
       mechanics. See also string theory.

The Free On-line Dictionary of Computing (30 December 2018):

string

    (Or "character string") A sequence of
   characters.

   Most programming languages consider characters and strings
   (e.g. "124:shabooya:\n", "hello world") to be distinct from
   numbers, which are typically stored in fixed-length binary
   or floating-point representation.

   A bit string is a sequence of bits.
