(Central Processing Unit)

Central Processing Unit

The Central Processing unit performs basic commands and instructions inside a computer.

On large machines, CPUs require one or more printed circuit boards. On personal computers and small workstations, the CPU is housed in a single silicon chip called a microprocessor. Since the 1970s the microprocessor class of CPUs has almost completely overtaken all other CPU implementations. Modern CPUs are large scale integrated circuits in packages typically less than four centimeters square, with hundreds of connecting pins.

The CPU becomes very hot inside a computer so it has to have its own heat sink and fan. If it over heats the computer would become very slow and would not word to its full capacity, so if the heat extractor isn't sufficient the computer will be slow even if its top of the range.
