Question 2

Define logic circuit

Answer 2

These are formed from a combination of logic gates and designed to carry out a particular task; the output from a logic circuit will be 0 or 1

Question 3

Define truth table

Answer 3

A method of checking the output from a logic circuit; a truth table lists all the possible binary input combinations and their associated outputs; the number of outputs will depend on the number of inputs.

Question 4

Define Boolean algebra

Answer 4

A form of algebra linked to logic circuits and based on TRUE or FALSE
