This article mainly introduces the meaning of the network cpu, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

CPU, which means central processing unit, is the most critical and core part of the computer. It not only represents the performance of the computer, but also determines the price of the computer to a great extent. it contains logic components, registers and control components.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

CPU means CentralProcessingUnit, the central processing unit, is the most critical and core part of the computer. It represents the performance of the computer, but also determines the price of the computer to a great extent.

CPU contains logic components, registers and control components. The logical unit is the part of CPU that is used for operation. Because electronic circuit components use binary logic operations, they are called logic components. A register is the place where data is temporarily stored. CPU carries out a large number of operations, if there is no certain storage space support, then the operation will not be carried out, and the results will be lost. The control unit is the part that controls the logic components and registers to coordinate the work. It is the brain of CPU.

The so-called computer is a machine that can perform a large number of operations in a short time. And CPU is its core component. The CPU mainly includes an arithmetic unit, that is, a very large-scale integrated circuit. Supercomputers can perform more than trillions of calculations per second, thanks to arithmetic machines. The efficiency of CPU is often expressed by the main frequency. The common unit of main frequency is GHz. Generally speaking, the main frequency of CPU can reach 2-2.5GHz, which is the mainstream computing power in the market. This kind of CPU includes AMD's high-end series, core I5 low-voltage series and so on. It can probably be accelerated to more than 3GHz with Rui frequency, but it generally does not exceed 3.5GHz.

CPU has such a high computing performance, naturally accompanied by quite high heat production. Near the CPU, where the graphics card is, the surface temperature can reach 46 degrees Celsius or higher. Therefore, it is very important to cool the CPU. In the computer, CPU will have a small fan that comes with it to cool down the CPU. Overheating of CPU may cause the computer to crash, or even burn the motherboard, or even cause a fire. Therefore, moderate use of computers is also very important.

Thank you for reading this article carefully. I hope the article "what is the meaning of network cpu" shared by the editor will be helpful to everyone? at the same time, I also hope that you will support and pay attention to the industry information channel, and more related knowledge is waiting for you to learn!
