About The CPU
CPUs are different depending on what computer type you are using. On large computers, one or more printed printed circuit boards (used to connect electronic components) are needed. On personal computers and laptops, CPUs can be found in a single silicon chip called a microprocessor. Two typical components of a CPU are an Arithmetic Logic Unit (ALU) and a Control Unit (CU). The ALU performs the mathematical things, and the CU extracts instructions from the Memory and executes them.
The History of the CPU
Procedures of CPUs
The program in the hard disk is transferred to the RAM (random access memory) memory.
The CPU uses a circuit called Memory Controller to load the program data from the RAM memory.
The data is now inside the CPU, where it is processed.
The program then tells the CPU what to do, like carry on loading some more or display something on screen.
