A central processing unit (CPU), also called a central processor, main processor, or just processor, is the primary processor in a given computer. [ 1 ] [ 2 ] Its electronic circuitry executes instructions of a computer program , such as arithmetic , logic, controlling, and input/output (I/O) operations.
In computing and computer science, a processor or processing unit is an electrical component (digital circuit) that performs operations on an external data source, usually memory or some other data stream. [1]
Because computer parts contain hazardous materials, there is a growing movement to recycle old and outdated parts. [66] Computer hardware contain dangerous chemicals such as lead, mercury, nickel, and cadmium. According to the EPA these e-wastes have a harmful effect on the environment unless they are disposed of properly.

The same computer might have several integer units, because these are relatively inexpensive, and can do the bulk of instructions. One kind of control unit for issuing uses an array of electronic logic, a "scoreboard" [5] that detects when an instruction can be issued. The "height" of the array is the number of execution units, and the "length ...

As fewer functions are left un-handled by the processor, chipset vendors have condensed the remaining northbridge and southbridge functions into a single chip. Intel's version of this is the "Platform Controller Hub" (PCH) while AMD's version was called Fusion Controller Hub (FCH). The PCH is still called a chipset. [5]
