CPU: The abbreviation of English Central Processing Unit, that is, Central Processing Unit, is a very large scale integrated circuit, which is the computing Core and Control Unit of a computer. Including Arithmetic Logic Unit (ALU), Cache, and Bus to realize the Data, control and status of their relationship.

Motherboard: Also known as mainboard, systemboard or motherboard, it is generally a rectangular circuit board, on which the main circuit system of the computer is installed, generally including BIOS chip, I/O control chip, key and panel control switch interface, indicator connector, expansion slot, DC power supply connector of motherboard and card, etc.

2. Different functions: The function of CPU is mainly to interpret computer instructions and process data in computer software, including processing instructions, executing operations, controlling time, processing data, etc. Together with internal Memory and input/output (I/O) devices, it is called the three core components of electronic computer.

Motherboard, installed in the chassis, is one of the most basic and important components of a computer. Many important accessories, such as CPU, memory, graphics card, chipset, etc., are directly placed on the motherboard, and they are also carriers that support the normal operation of hard disks, optical drives, etc.

Expand information:

CPU is the central processing unit, which includes a controller and an arithmetic unit. Motherboard is a place where hardware relies on contact, mainly for transmitting information. Only when the CPU is plugged into the motherboard can it run with other hardware on the motherboard. Simply put, if you compare a computer to a human being, then the CPU is the human brain, and the motherboard is the carrier and support of the human body, just like the skeleton. The CPU runs on the motherboard, and the two are different.
