CPU
Alternately referred to as a processor, central processor, or microprocessor, the CPU is the Central Processing Unit of the computer. The CPU handles all instructions it receives from hardware and software running on the computer. The CPU chip is usually in the shape of a square or rectangle and has one notched corner to help place the chip properly into the CPU socket. On the bottom of the chip are hundreds of connector pins that plug into each of the corresponding holes in the socket. Today, with slot processors that were much larger and slid into a slot on the motherboard. Also, over the years, there have been dozens of different types of sockets on motherboards. Each socket only supports specific types of processors and each has its own pin layout.
The CPU was first developed at Intel with the help of Ted Hoff and others in the early 1970's. The first processor released by Intel was the 4004 processor. In the past, computer processors used numbers to identify the processor and help identify faster processors. For example, the Intel 80486 processor is faster than the 80386 processor. After the introduction of the Intel Pentium processor, all computer processors started using names like Athlon, Duron, Pentium, and Celeron. in addition to the different names of computer processors, there are different architectures 32-bit and 64-bit, speeds, and capabilities.
Cpu is an electronic circuit within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output. Electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow.
The combination of components and wires allows various simple and complex operations to be performed signals can be amplified, computations can be performed, and data can be moved from one place to another. Circuits can be constructed of discrete components connected by individual pieces of wire, but today it is much more common to create interconnections by photolithographic techniques on a laminated substrate and solder the components to these interconnections to create a finished circuit.
