Central Processing Unit (CPU)

The central processing unit (CPU) is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the functions of the computer or other processing device. It carries out each instruction of the program in sequence, to perform the basic arithmetical, logical, and input/output operations of the system. In other words, the CPU is the "brains" of the computer. The term has been in use in the computer industry at least since the early 1960s.
