The history of the microprocessor

In November of 1971, a company called Intel publicly released the worlds first single chip processor. It was know as the Intel 4004. And was invented by Intel engineers Federico Faggin, Ted Hoff, and Stanley Mazor. The Intel 4004 took the integrated circuit (a circuit that is built into a device) a step further. They did this by placing every part of a computer that made it 'think' (i.e. central processing unit (CPU): the memory, input and output controls) into one small chip. This made the Programming intelligence in inanimate objects possible.

What is a microprocessor?

A microprocessor (CPU) is the brain of the computer, the central processing unit (CPU) also consists of the control unit and the arithmetic/logic unit, these both function together to form and process the users commands , the control unit's job is to control how the events in the processor flow. The unit collects instructions from memory and decodes them into a language that the computer can understand (binary). The arithmetic/logic handles all the mathematical calculations and solve logical problems. It then takes the commands from the control unit and executes them, once this is done it then stores the results back into the memory. These 4 steps, (collects, decode, execute, and store), are what's called the "machine cycle" of a computer.
