1. clock speed The clock speed is also called the clock frequency. The unit is MHz, which indicates the computing speed of the CPU. CPU clock speed = frequency X frequency doubling coefficient. Many people think that the clock speed determines the CPU running speed. This is not only one-sided, but also a misunderstanding of the server. So far, there is no definit

The information is as follows: 2011-2-15 (Tuesday) 17:50 Warning-load average:9.73, 10.67, 10.49 There are also alert messages issued in the first two hours: 2011-2-15 (Tuesday) 16:50 Warning-load average:10.52, 10.10, 10.06 2011-2-15 (Tuesday) 15:40 Warning-load average:8.27, 9.23, 9.48 first, what does the

Computer use for a long time, it is inevitable that such a failure. In many computer failures, board card class appears the most likely. Although the CPU is an important part of the computer, but the probability of failure is relatively small, common CPU failures are roughly the following: thermal failure, restart failure, black screen fault and overclocking failure. Because the

CPU Cache Most CPUs only have Level 1 cache and level 2 cache, and some have Level 3 cache.The cache memory is the temporary memory between the CPU and memory. It has a smaller capacity than the memory but is faster than the memory. The data in the cache is a small part of the memory, but this small part is about to be accessed by the CPU in a short time. When th

Therefore, this time, we will learn about our processor through the system and simple software methods.
