WHAT IS CPU:

                                      CENTRAL PROCESSING UNIT (CPU)
Pronounced as separate letters, process unit|CPU|C.P.U.|central processor|processor|mainframe|electronic equipment|hardware|computer hardware} is that the abbreviation for central processing unit. typically remarked merely because the central processing unit, however a lot of unremarkably referred to as processor, the CPU is the brains of the pc wherever most calculations take place. In terms of computing power, the CPU is that the most significant component of a computing system.
On giant machines, the CPU needs one or a lot of computer circuit boards. On personal computers and tiny workstations, the CPU is housed in an exceedingly single chip referred to as a chip. Since the 1970's the chip category of CPUs has virtually utterly overtaken all different CPU implementations.
The CPU itself is an inside element of the pc. fashionable CPUs square measure tiny and sq. and contain multiple metallike connectors or pins on the bottom. The CPU is inserted directly into a CPU socket, pin aspect down, on the motherboard.
Each motherboard will support only a particular type (or range) of CPU, therefore you need to check the motherboard manufacturer's specifications before trying to interchange or upgrade a CPU in your pc. fashionable CPUs even have associate hooked up sink and tiny fan that go directly on prime of the CPU to assist dissipate heat.
Two typical parts of a CPU square measure the following:
1:The arithmetic logic unit (ALU), that performs arithmetic and logical operations.
2:The management unit (CU), that extracts directions from memory and decodes and executes them, line of work on the ALU once necessary.
