CPU. You may have heard the term clock speed.. It refers to the speed of your computer's central processing unit or CPU. Often called the brain of the computer, the CPU processes the instructions that programmers write when they create applications.ardware makers measure a CPU's clock speed using a unit called gigahertz.
