*Control Unit: retrieves, breaks down and executes instructions.*Logic Gates: Controls the flow of information*Arithmetic and Logic Unit: Performs arithmetic and logical operations on data.*Internal Clock: ensures circuits work together at the same time. *Internal Buses: connects and interacts with internal computer components. *Registers: Stores data, waiting for instructions for them to be executed. The main component of a processor is silicon and the second main component is the transistor. Silicon is a natural element found in the earth's crust and has the characteristics to make it a semiconductor. A transistor is an electrical component which can play two roles, an amplifier or a switch. The first step in the process of creating a processor is to melt silicon with electrical active elements such as arsenic, boron, phosphorus or antimony.
