What is a microprocessor and how is it made?
Simply put, a microprocessor is the brain of your computer. Intel, AMD, or any other range of manufacturers. It doesn’t matter. At the end of the day the microprocessor (CPU) does calculations as quickly and efficiently as possible (read: thinking really fast, using little power).
If you want to get technical:
“A microprocessor is a computer processor that incorporates the functions of a computer’s central processing unit (CPU) on a single integrated circuit (IC), or at most a few integrated circuits. The microprocessor is a multipurpose, programmable device that accepts digital data as input, processes it according to instructions stored in its memory, and provides results as output. It is an example of sequential digital logic, as it has internal memory. Microprocessors operate on numbers and symbols represented in the binary numeral system.” – Wikipedia
So basically lots of little switches jammed into a small space and all connected to calculate billions of 1’s and 0’s. If you want to watch the interesting process of CPU manufacturing, refer bellow:
