Microprocessor

A microprocessor (abbreviated as µP or uP) is a computer electronic component made from miniaturized transistors on a single semiconductor integrated circuit (IC) (aka microchip or just chip). The central processing unit (CPU) is the most well known microprocessor, but many other components in a computer have them, such as the GPU on a video card.
