A processor is essentially the heart of the computer. Its speed is measured by how many times it vibrates each second, much like a heart rate is measured by how many times it pumps blood per minute.
Measurement
The speed of a processing unit is determined by how many cycles it goes through each second. A 2 GHz processor has 2 billion cycles each second.
Benefits
The speedier a processor is, the more instructions it can carry, essentially making it more powerful. Many other factors can affect how fast it does what it has to, however.
FLOPS
Processing speed sometimes is interpreted in units of FLOPS (Floating Point Operations Per Second). This unit shows how fast the processor performs mathematical operations.
Front Side Bus Speed
Another way of measuring processing speed is by determining how fast the processor can communicate with the other devices in a computer. This measurement is known as the FSB speed, or Front Side Bus.
Misconceptions
The first thing that attracts prospective customers when purchasing a processor is the clock speed of the processor. It is often recommended to look at other factors that can affect how fast the processor will deliver information by using a combination of its different aspects to judge how well it performs, such as how many FLOPS it can do and its FSB speed.
