The Central Processing Unit Microprocessors, also called central processing units (CPUs), are frequently described as the "brains" of a computer, because they act as the central control for the processing of data in personal computers (PCs) and other computers. Chipsets perform logic functions in computers based on Intel processors. Motherboards combine Intel microprocessors and chipsets to form the basic subsystem of a PC. Because it's part of every one of your computer's functions, it takes a fast processor to make a fast PC. These processors are all made of transistors. The first trans
