    Central Processing Unit

    A central processing unit (CPU), or sometimes simply processor, is the component in a digital computer that 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.

    The phrase "central processing unit" is a description of a certain class of logic machines that can execute computer programs. This broad definition can easily be applied to many early computers that existed long before the term "CPU" ever came into widespread usage. However, the term itself and its initialism have been in use in the computer industry at least since the early 1960s (Weik 1961). The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation has remained much the same.

    Early CPUs were custom-designed as a part of a larger, usually one-of-a-kind, computer. However, this costly method of designing custom CPUs for a particular application has largely given way to the development of mass-produced processors that are suited for one or many purposes. This standardization trend generally began in the era of discrete transistor mainframes and minicomputers and has rapidly accelerated with the popularization of the integrated circuit (IC). The IC has allowed increasingly complex CPUs to be designed and manufactured in very small spaces (on the order of millimeters). Both the miniaturization and standardization of CPUs have increased the presence of these digital devices in modern life far beyond the limited application of dedicated computing machines. Modern microprocessors appear in everything from automobiles to cell phones to children's toys.

    CPU stands for Central Processing Unit. In every PC, there's a monitor, a big rectangular box which is the CPU and speakers (if urs is not integrated into ur monitor). The monitor displays the graphics so u can see the softwares/programmes u're running. The CPU is the one which inputs all these info. For instance, CPU contains the harddisk drive where u store ur documents and the softwares u installed, graphics card to allow graphics input for ur monitor to display graphics and all the text and pics u see on ur monitor screen, CD/DVD drive to playback and write (burn) CD/DVD. And of course, there's a motherboard which connects all these devices together to a central board. In short, it stores everything u need to make a computer workable like a brain. Without it, ur monitor won't even display anything except for a blank screen. Which is why, it's termed Central Processing Unit. =)

    The CPU or Central Processing Unit is the little square or rectangular piece of hardware (microprocessor) on your computers motherboard that understands computer programming instructions and processes all the data..it executes all of the computers programs or software

    cpu stands for computer procesing unit i think probebly not but its what makes the computer run stuff and the better cpu you have the faster ur apps with run

    its the part of the computer thats NOT the monitor. alot of people refer to the monitor as the computer but really in acutality, its the um...i dont know how to explain it but this...its the large box looking thing next to it. the one with the CD drive and power button on it.

    well. yes.
