Description A CPU processor is a computer chip about the size of a matchbook. Inside the package is a silicon rectangle containing millions of transistorized circuits.

One of the most important parts of a processor is the buffer memory, also called the cache. What is it responsible for and how does it work?

Cores and threads Each processor has a certain number of cores, which essentially work like independent mini-processors within the primary computer processor.

Processors work according to a clock that beats a set number of times per second, usually measured in gigahertz. For instance, a 3.1-GHz processor has a clock that beats 3.1 billion times per second.

Your standard computer processor is on the larger side and consumes a fair amount of power, but it gets the job done as far as math is concerned, crunching numbers with pinpoint accuracy.

Your next office machine doesn't need a ton of CPU power to deliver a great office and everyday computing experience.
