Meaning of CPU in English
Stands for "Central Processing Unit." This baby is the brain of your computer. It processes all basic instructions and pretty much runs the show.

It just keeps on processing. Amazing. The CPU is also referred to as the simply the processor. Some people refer the entire motherboard as the CPU, but that's just wrong.
