A central processing unit (CPU) is a piece of hardware that is responsible for allowing your computer to interact with the applications and programs installed on it. The amount of cores within a processor determines how much information can be transmitted at a time and as well as how quickly that information can be transmitted. A processor core are individual units within a CPU. Each core is responsible for its own individual tasks requested by the user. Clock speed is the unit of measurement that determines the duration it takes for a CPU to retrieve and interpret instructions. The unit of measurement for clock speed is gigahertz (GHz). The higher the gigahertz, the faster the clock speed. A modern processor can handle upto a trillion calculations per second. Most computers sold today either come equipped with either an Intel, AMD or Apple processors. While CPU’s handle the inputs and outputs of applications within a computer, a GPU processor is designed to handle graphical outputs on your monitor. Both CPU and GPU are the main components that make up a computer.
