What is "CPU"?

The CPU (Central Processing Unit) is a program executor in the form of an electronic circuit, it is commonly known as a processor. Once only available in computing machines like PCs, CPU?s are now widely used in the mobile arena, being the hardware brains of tablets and smartphones. In terms of judging performance the clock rate is one of the core characteristics to check. The clock rate is the cycle in seconds for the clock within the CPU, although comparisons for performance can only really be conducted with chips from the same family, if clock rate is being used as a key factor.

CPU?s these days are microprocessors, meaning they are constructed as one single integrated circuit.
