scalar
     
        1.  a single number, as opposed to a vector or
        matrix of numbers.  thus, for example, "scalar
        multiplication" refers to the operation of multiplying one
        number one scalar by another and is used to contrast this
        with "matrix multiplication" etc.
     
        2.  in a parallel processor or vector
        processor, the "scalar processor" handles all the sequential
        operations - those which cannot be parallelised or vectorised.
     
        see also superscalar.
     
        3.  any data type that stores a single value
        e.g. a number or boolean, as opposed to an aggregate
        data type that has many elements.  a string is regarded as a
        scalar in some languages e.g. perl and a vector of
        characters in others e.g. c.
