  3. 5. What circuits do clocks use to tell time?
  4. 9. What type of gate outputs a 1 if both inputs are different?
  5. 10. What kind of circuit does a computer use for basic addition?
  6. 11. A combination of interacting gates for a specific function.
  7. 12. Cpu's use what type of connection when place into a motherboard?
  8. 14. This kind of representation lists all possible input and output values of a gate.

  10. 18. What type of gate does this represent? (Q = A + B).
  11. 19. A gate represented in Boolean Algebra by X = AxB
  12. 22. This circuit produces one output value by choosing from several input values.
  13. 23. What is a circuit that adds two binary digits and produces a sum and a carry?

  4. 7. What invention led to the first initial downsizing of computers?
  5. 8. What is a graphical representation of a circuit called?
  6. 13. A device that performs a basic operation on electrical signals.
  7. 15. This type of algebra is used to represent circuits and gate.
  8. 16. What type of gate requires all conditions to be met before outputting a value?
  9. 20. What type of gate does a 0 becomes a 1 and vice versa?
  10. 21. Represented in a Logic-Diagram by a right facing arrow with a line behind it.
  11. 24. This type of gate uses a NOT operator and a multiplication sign in its Boolean expression.
