| | Central Processing Unit - MSN Encarta |
 | | In the first computers, CPUs were made of vacuum tubes and electric relays rather than microscopic transistors on computer chips. | | | These ideas include quantum computing, in which single atoms hold bits of information; molecular computing, where certain types of problems may be solved using recombinant DNA techniques; and neural networks, which are computer systems with the ability to learn. | | | Experimental ideas in computing may radically change the design of computers and the concept of the CPU in the future. |

| | Central Processing Unit - Wikipedia |
| | Often abbreviated "CPU", this is the part of a computer that interprets and performs the instructions given to it by software. | | | The term is often used vaguely to include other centrally important parts of a computer such as storage and input/output control, especially in computers with modern microprocessor chips that include several of these functions in one physical semiconductor chip. | | | In many computers, this is further divided into a control unit that handles program flow and an arithmetic and logical unit that performs operations on data. |

| | Central Processing Unit Summary - Central Processing Unit Information |
| | The integration of CPU and other computer functions on the same microprocessor chip has blurred the distinction between a computer and its CPU. | | | The smallest memory components are generally placed the closest to central processing components in order to optimize performance for the majority of processing operations. | | | The CPU, therefore, functions as the heart of the computer, facilitating all data processing activity. |

| | Central Processing Unit (CPU) - The main part of the computer, its 'brain', consisting of the central memory, arithmetic logic unit and control unit. | | | Memory Unit - Part of the computer where data and instructions are held. | | | Also, anything in the CPU that is to be stored in main memory comes here first before being copied into the main memory at the location specified by the address containd in the MAR. |

| | Central Processing Unit |
| | As you might expect from its name, the central processing unit is the heart of the computer and this is where all the computing is done. | | | The Arithmetic and Logic unit is responsible for doing the actual computing and so can be considered to be the brain of the computer (see figure 9). | | | Cache that is in the CPU is referred to as Level 1 cache, and is usually quite small while the larger level 2 cache is outside, but close to the CPU. |

| | The Central Processing Unit |
| | Before the CPU can execute a program, program instructions and data must be placed into memory from an input device or storage device. | | | Memory is the part of the computer that stores data and program instructions for processing. | | | Regardless of the design and processing strategy of a computer, its goal is the same: to turn raw data into useful information. |

| | Among other tasks carried out are the control of input and output devices and the passing of data to the Arithmetic/Logical Unit for computation. | | | In addition to computation the CPU controls and co-ordinates the operation of the other major components. | | | It is worth noting here that the only operations that the CPU can carry out are simple arithmetic operations, comparisons between the result of a calculation and other values, and the selection of the next instruction for processing. |

| | Central Processing Unit (CPU) |
| | The CPU is composed of logic gates that accept input, process it and produce output. | | | The Central Processing Unit (CPU) is the brain of the computer. | | | The complete CPU usually contains a core processor with two or more pipelines, a dedicated arithmatic logic unit (ALU, also called the math co-processor), and special high-speed memory in some cases for caching program instructions from RAM. |

| | For example, the CPU runs the operating system, the software programs installed on your computer, and device peripherals such as printers and flatbed scanners. | | | If purchasing a personal computer the "processor" or "CPU" (abbreviation for Central Processing Unit) will have a significant factor towards the cost of your computer system-- the newer and more powerful the CPU, the more expensive the computer system will be. | | | The processor is responsible for everything your computer does. |

| | The 8086 from 1978 was the first 16 bit CPU from Intel using a 16 bit system bus. | | | CPU history starts in 1971, when a small unknown company, Intel, for the first time combined multiple transistors to form a central processing unit - a chip called Intel 4004. | | | Since the CPU carries out a large share of the work in the computer, data pass continually through it. |

| | The control unit fetches instructions from memory and decodes them to produce signals which control the other part of the computer. | | | Designs vary widely but, in general, the CPU consists of the control unit, the arithmetic and logic unit (ALU) and memory (registers, cache, RAM and ROM) as well as various temporary buffers and other logic. | | | A parallel computer has several CPUs which may share other resources such as memory and peripherals. |

| | CENTRAL PROCESSING UNIT |
| | The Central Processing Unit, or CPU, is the brains of the computer. | | | In fact, there are 370 of them, each leading to various components on the board. | | | Anyway, notice the "wires" leading from away from each "pin." The pins on the CPU are in contact with those silverish things sticking out of the back of the board, and little goldish wires, embedded in the motherboard, connect each one to another area on the board. |
