The difference is as follows:
First, the subject is different
1, the motherboard: installed in the chassis, is the most basic and one of the most important components of the computer.
2, CPU: is the computing and control core of the computer system, is the final execution unit of information processing and program operation.
Second, the principle is different
1, the main board: the use of open structure. Most of the motherboards have 6-15 expansion slots for the PC peripheral control card (adapter) to plug in.
2, CPU: The process of taking an instruction from the main memory to the instruction register. A number in the program counter that indicates the position of the current instruction in main memory. When an instruction is fetched, the value in the PC is automatically incremented according to the instruction word length.
Three, the role is different
1, motherboard: installed the main circuit system of the computer, there are BIOS chip, I\/O control chip, keyboard and panel control switch interface, indicator connector, expansion slot, motherboard and card DC power supply connector and other components.
2, CPU: The function is mainly to interpret computer instructions and process data in computer software.
The CPU is near the memory, and the memory is near the hard disk.
CPU is the most important component of mobile phone. It's easy to tell the difference.
In general, the logical part is in the lower part of the mobile phone motherboard. The logical part includes: CPU, power supply, font library, temporary storage. The largest of them, the square, is the CPU.
The power supply should be small and square. The font is rectangular. Now the machine's temporary storage is basically integrated with the font library.
1. The memory and CPU of the mobile phone motherboard have obvious differences.
2. The CPU is generally a black flat cuboid with a small solder joint, while the memory is generally a silver cuboid with a larger solder joint.
