uniprocessor

[′yü·nə‚prä‚ses·ər]
(computer science)
A computer that has a single central processing unit and works sequentially on only one program at a time.

uniprocessor

(processor)
(From "uni" - one) A computer with a single central processing unit, in contrast to a parallel processor. Most personal computers are currently (March 1997) uniprocessors. Some more expensive computers, typically servers, have multiple processors to provide increased throughput.

See also symmetric multiprocessor and massively parallel processor.

uniprocessor

A single processor. As more and more computers employ multiprocessing architectures, such as SMP and MPP, the term is used to refer to a system that still has only one CPU. Although most desktop computers are uniprocessor systems, it is expected that dual processor systems will become commonplace on the desktop in the coming years.
