FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -CPU clock speed is a good indicator of overall processor performance.

Detailed explanation-2: -The clock speed is determined by a quartz-crystal circuit, similar to those used in radio communications equipment. Computer clock speed has been roughly doubling every year. The Intel 8088, common in computers around the year 1980, ran at 4.77 MHz. The 1 GHz mark was passed in the year 2000.

Detailed explanation-3: -A CPU’s clock speed represents how many cycles per second it can execute. Clock speed is also referred to as clock rate, PC frequency and CPU frequency. This is measured in gigahertz, which refers to billions of pulses per second and is abbreviated as GHz.

Detailed explanation-4: -In general, a higher clock speed means a faster CPU. However, many other factors can come into play, as well. Your CPU processes many instructions from different programs every second. Some of these instructions involve simple arithmetic, while others are more complicated.
