  45. The Central Processing Unit (CPU) is the only portion of the computer that can perform binary arithmetic.[16]
  46. Everything else that is going on in the computer system boils down to binary arithmetic that the CPU must do.[16]
  47. This binary arithmetic work that the CPU performs for all of the other components is called processing.[16]
  48. Below we see a simplified diagram describing the overall architecture of a CPU.[17]
  49. But really, in a nutshell, it comes down to how much computing can be done when all parts of a CPU come together in a single clock cycle.[17]

  82. Intel 4004 in 1971 and Intel 8080 in 1974 dominated all other CPU implementation.[26]
  83. All computers years ago were called "mainframes," and the CPU referred to the entire computer.[27]
  84. Also called the "processor," the CPU is made up of the control unit, which executes the instructions, and the ALU, which performs the calculations and logical operations.[27]
  85. See microprocessor control unit and ALU Technically, the CPU, clock and main memory make up a computer.[27]
  86. In addition to the CPU, a complete computer system requires input/output channels, peripheral control units, storage devices and an operating system.[27]
