A computer's processor is the control center for the computer, and it carries out the computations that allow the computer to function. The circuits in this central processing unit (or CPU) send commands to the other components of the computer to run programs, accept input and produce output.Know More
The CPU retrieves information from the computer's memory and conducts operations on that information. The CPU thus operates like the working memory of a person's brain; it takes information from long-term storage when it is needed for immediate processing. In this way, the CPU operates as a general-purpose information processor, which can accommodate different types of information from other parts of the computer.
Every computer has a processor, but the exact type of processor varies between different computers. Macs and PCs use different CPUs, and there are various manufacturers of processors for each system. Some systems run parallel processors, which allow multiple operations to run simultaneously.
The operations in the processor are simple binary computations using electrical circuits. These computations are carried out extremely quickly; a standard computer's processor can carry out millions of calculations per second, while supercomputers reach into billions of computations per second. However, most programs require a massive number of such calculations to carry out, which is why computer operations do not operate instantaneously.Learn More
A computer monitor is a hardware component of a computer that displays information through a visual interface. The monitor is composed of a case and a screen that displays the information.Full Answer >
A CPU is the brain of a computer, according to About.com's Tim Fisher. Short for "central processing unit," the CPU interprets commands before executing them. The CPU is also called a processor or central processor.Full Answer >
A computer keyboard allows an operator to give commands to the computer in a simple way by pressing keys. The keys on a keyboard are typically labeled with their input function, ranging from letters of the alphabet to numbers and symbols.Full Answer >
