Computer 400MHZ describes the main frequency of the cpu, is the speed of the digital pulse signal oscillation in the cpu, that is, 400M times per second often said: "The frequency of the CPU is how much" in fact, this general frequency refers to the CPU frequency, the main frequency is the CPU clock frequency, the English full name: CPU Clock Speed is simply the working frequency of the CPU.
MHz refers to the frequency performance of an electronic device with a frequency of 400 million times per second. In generalThe higher the frequency, the faster the device will operate. As a result, 400MHz is used in many high-speed devices, such as cpus, Gpus, and networking devices. By increasing the frequency, these devices are able to process large amounts of data and tasks faster. Of course, 400MHz is not the higher the better.
