Integrated circuit

A chip (IC) is a microelectronic device that integrates multiple components. According to its function and structure, it can be divided into three categories: analog integrated circuits, digital integrated circuits, and digital/analog hybrid integrated circuits. The central processing unit (CPU) is a very large-scale digital integrated circuit (this shows that the CPU is just a kind of chip), mainly composed of arithmetic units, controllers, registers and buses, and is the computing core and control core of a computer.
