Across
  1. 5. a circuit that performs addition using inputs from A and B only.
  2. 8. a circuit that performs addition using inputs from A and B plus a carry bit
  3. 10. the result is true if both inputs are true.
  4. 11. result is true if either input is true
  5. 12. inverts the result so true becomes false and false becomes true.
  6. 13. result is true if both inputs are false
  7. 14. a combination of logic gates
  8. 15. a memory unit that changes state with each pulse of the clock
  9. 16. a device that generates a signal used to synchronise the components of a computer.
Down
  1. 1. result is true if either input is true but not if both are true
  2. 2. a memory unit that can store one bit.
  3. 3. an equation made up of Boolean operations
  4. 4. used to store 0 or 1 depending on the result binary addition
  5. 6. part of the processor that processes and manipulates data
  6. 7. result is true if any of the inputs are false
  7. 9. an electronic component used to perform Boolean Algorithms
