     [1913 Webster]

From WordNet (r) 3.0 (2006) :

      n 1: the quality of being light enough to be carried

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

      The ease with which a piece of
     software (or file format) can be "ported", i.e. made to run
     on a new platform and/or compile with a new compiler.
     The most important factor is the language in which the
     software is written and the most portable language is almost
     certainly C (though see Vaxocentrism for counterexamples).
     This is true in the sense that C compilers are available for
     most systems and are often the first compiler provided for a
     new system.  This has led several compiler writers to compile
     other languages to C code in order to benefit from its
     portability (as well as the quality of compilers available for
     The least portable type of language is obviously assembly
     code since it is specific to one particular (family of)
     processor(s).  It may be possible to translate mechanically
     from one assembly code (or even machine code) into another
     but this is not really portability.  At the other end of the
     scale would come interpreted or semi-compiled languages
     such as LISP or Java which rely on the availability of a
     portable interpreter or virtual machine written in a lower
     level language (often C for the reasons outlined above).
     The act or result of porting a program is called a "port".
     E.g. "I've nearly finished the Pentium port of my big bang
     Portability is also an attribute of file formats and depends
     on their adherence to standards (e.g. ISO 8859) or the
     availability of the relevant "viewing" software for different
     platforms (e.g. PDF).
