What is the speed of the clock?

The speed or speed of the computer is the speed at which the central processing unit (CPU) is able to perform basic functions. It is normally measured in Megahertz or millions of cycles per second, or even Gigahertz, which are billions of cycles per second. The speed of hours is useful to compare the speed of chips made by the same companies, but is not a reliable way to compare different types of computers, as many other factors can determine the speed of the computer. Instead, computers should be compared on the basis of how specific tasks are performed, such as loading graphics or calculating.

All computers have hours that emit regular electric pulses that help computer to synchronize the timing of the tasks required. CPU requires the command to make a certain number of hours or pulses from the computer lesson. The number of cycles that the computer can reach in the second second determines the speed of hours. The first computers created by IBM in The TheTK 80. He had a speed of about 4.77 MHz, which is about 5 million cycles per second. By 2010, the average computer could be measured in the GHz.

Although the frequency of hours most often refers to the CPU speed, other devices on the computer also have hours. The expansion of buses that allow the computer to be modified by means of printed circuits are controlled by internal clocks. Memory with random access (RAM), reading memory and writing used to do work when the computer runs, and also uses hours.

CPU can only process as quickly as other components on the computer. If the expansion bus or RAM is slower than the central processing unit, the computer will not be launched as quickly as the CPU allows. In addition, some processors can perform different tasks at different speeds. For example20 before performing the same task. For this reason, the speed of hours is not a reliable way to compare computers.

Benchmarks are a more reliable source of comparison. Several organizations offer reliable and monitored standard benchmarks. These include standard performance evaluation (Spec), transaction (TPC) and built -in microprocessor benchmark Korsortium (EEMBC). These companies operate computers through a number of carefully controlled tests to determine how fast each of them performs specific tasks. The numbers are published free of charge on the organization's website.
