  4. ALU
    Arithmetic and logic unit: a part of the computer that performs arithmetic operations, logic operations, and related operations.
  5. analog data
    The representation and measurement of the performance or behavior of a system by continuously variable physical entities such as currents, voltages and so on.
  6. digital data
    Discrete data
  7. and
    The output of "and" is True if all statements are True, False if any statement is False.
