  2. Central Processing Unit (CPU) • The basic CPU is composed of five different elements • Each element was designed with Gates • Each Gate was made with transistors

  3. Simple Central Processing Unit • The five basic CPU elements are: • Instruction fetcher • Instruction decoder • Registers • Arithmetic Logic Unit • Memory Unit

  4. Instruction fetcher • Picks up the next instruction for the CPU

  5. Instruction decoder • Implements the instruction by controlling the other hardware.

  6. Registers • Short term memory • Holds data for processes, like adding two numbers.

  7. Arithmetic Logic Unit • Performs arithmetic functions: • Addition, subtraction, multiplication • Logic functions like AND and OR

  8. Memory Unit • Handles fetching and storing of data
