- - - - BIOS
      - non-volatile
    - - volatile
  - - - ascii (8 bit american)
      - unicode (all languages)
- - - - MAR (stores the address of instructions to be fetched)
      - MDR (stores currently fetches instructions)
      - Program counter (increments by 1 every time an instructions is carried out (stores next instruction))
      - ACC (stores the result of the instruction)
    - - Value in the program counter copied to the MAR. The instruction at the address stored in the MAR is fetched from RAM and stored into the MDR. The program counter is incremented.
        The instruction in the MDR is decoded.
        The decoded instruction is executed.
        The process is repeated.
    - - 3 levels
    - - Clock speed (number of instructions that can be performed per second)
      - No. of cores (multitask)
      - Amount of cache (too much cache is a thing)
