(computer science)
A computer that carries out computations on one number at a time.

scalar processor

A CPU that performs computations on one number or set of data at a time. Most computers have scalar CPUs. A scalar processor is known as a "single instruction stream single data stream" (SISD) CPU. Contrast with vector processor. See scalar.
