How does it work
How does it work? Where does it come from?
The microprocessor chip is the centre of any computer, if its a desktop, laptop or ipad or anything which needs a computer processor the microprocessor is what controls it all. It is the reason why our computer works and executes our commands. The microprocessor you are using might be a Pentium, a K6, a PowerPC, a Sparc or any of the many other brands and types of microprocessors, but they all do approximately the same thing in approximately the same way.
A microprocessor is a complete computation engine that is fabricated on a single chip. The first microprocessor was the Intel 4004, introduced in 1971. The 4004 was not very powerful as all it could do was add and subtract, and it could only do that 4 bits (16 nibbles) at a time. But it was amazing that everything was on one chip. Prior to the 4004, engineers built computers either from collections of chips or from discrete components. The 4004 powered one of the first portable electronic calculators.
