Central processing unit Definition from Computer & Internet Dictionaries & Glossaries

FOLDOC
central processing unit
<architectureprocessor> (CPU, processor) The part of a computer which controls all the other parts. Designs vary widely but, in general, the CPU consists of the control unit, the arithmetic and logic unit (ALU) and memory (registerscacheRAM and ROM) as well as various temporary buffers and other logic.
The control unit fetches instructions from memory and decodes them to produce signals which control the other part of the computer. This may cause it to transfer data between memory and ALU or to activate peripherals to perform input or output.
parallel computer has several CPUs which may share other resources such as memory and peripherals.
The term "processor" has to some extent replaced "CPU", though RAM and ROM are not normally considered as part of a processor. This is particularly true of common modern microprocessors though there have been microprocessors which include RAM and/or ROM on the same integrated circuit.
The CPU Info Center lists many kinds of CPU.

WebGuest Web Glossary
CPU - Central Processing Unit
The brains of your computer. In fact, the main silicon chip that runs the operating system and programs, and controls essential operations.

Jensen's Technology Glossary
CPU
Central Processing Unit that encompasses a computer's RAM, processing, and control circuitry, including the arithmetic-logic (ALU) unit. Both the ALU and the control units are wholly contained on the microprocessing chip whereas the primary storage is on the mother board or the expansion bus. For test comparisons of Intel Pentium, PowerPC, and Mips R4X00, and DEC Alpha, see Montgomery (1994) . Montgomery ranks Pentium and Mips highest in terms of file servers. He ranks Pentium higher on most graphics and business applications criteria except for price since PowerPC is a cheaper alternative. There are, of course, other considerations. The PowerPC currently performs better than Pentium in terms of temperature, speed, and price, but all these advantages are expected to disappear when Intel introduces its upgrade versions of the Pentium. The PowerPC, however, will not perform as well using DOS and Windows operating systems. (See also Alpha processor , Pentium , MIPS , PowerPC , CISC , RISC , Operating system , and Motherboard )

Electronic Music Glossary
Central processing unit (CPU)
A microprocessor or computer which is used to perform complex task-related functions. Within an electronic musical instrument, it is a dedicated computer system for handling the many performance and control-related messages and commands that must be processed in real time.

Wikipedia English - The Free Encyclopedia
Central processing unit
A central processing unit (CPU), or sometimes simply processor, is the component in a digital computer capable of executing a program. It interprets computer program instructions and processes data. CPUs provide the fundamental digital computer trait of programmability, and are one of the necessary components found in computers of any era, along with primary storage and input/output facilities. A CPU that is manufactured as a single integrated circuit is usually known as a microprocessor. Beginning in the mid-1970s, microprocessors of ever-increasing complexity and power gradually supplanted other designs, and today the term "CPU" is usually applied to some type of microprocessor.
