A computer's CPU is considered the "brain of the computer," being responsible for its major processes, like searching for information, sorting information, making calculations and advanced processes as well as decisions integral to the functioning of the computer. The acronym CPU actually stands for central processing unit and, as such, works behind virtually any task the user is doing on their computer, like writing essays, making photo albums or reading emails. The CPU is made out of a very complex silicon integrated circuit board mounted with tiny, microscopic transistors that can easily number in the billions.
