Understanding the Basics of Processor Manufacturing

What is a processor?

A processor, also known as a central processing unit (CPU), is the primary component of a computer that carries out instructions of a program. It performs the majority of the processing inside a computer, including arithmetic, logic, input/output operations, and controlling the flow of data between the memory and other components.

The term “processor” has been in use since the 1960s, but it wasn’t until the 1970s that the first microprocessors were developed. These early processors were small, cheap, and powerful, and they revolutionized the computing industry by making it possible to build personal computers that were affordable and accessible to a wider audience. Since then, processors have become more complex and powerful, and they are now found in virtually every type of computing device, from smartphones and tablets to servers and supercomputers.
