| Question | Answer |
| What is a logic gate? | The basic foundation of a digital circuit that controls the flow of electronic signals. |
| What is digital circuit? | A circuit where electronic signal are one of two values, high voltage(1) or low voltage(0). |
| What is voltage? | The potential difference across an electrical component needed to make electricity flow through it. |
| What is microprocessor? | An integrated circuit that provides the same function of a CPU. |
| What is truth table? | A way of showing every outcome of a logic gate. |
| What is an AND gate? | X can only be 1 if A and B are 1. Logical statements are known as Boolean statements. Statement for an AND gate is: X=A.B ADD LOGIC GATE IMAGE FROM BOOK |
| What is a truth table? Truth table of an AND gate. | Is a way of showing every outcome of a logic ate. ADD TABLE FROM BOOK |
| What is an OR gate? | X will be 1 if A or B is 1 (It can be 1 or more) Statement for an Or gate is: X=A+B. Sign (+) can be used to represent the word OR . ADD LOGIC GATE IMAGE FROM BOOK |
| Truth table of an OR gate? | ADD TABLE FROM BOOK. |
| What is a NOT gate? | X will only be 1 if A is 0. Statement of an NOT gate: - X=A or X=A' ADD LOGIC GATE IMAGE FROM BOOK. |
| Truth table of an NOT gate? | TABLE FROM BOOK |
| What is an NAND gate? | X will always be 1 unless A and B are 1. Statement of the NAND gate: ---- X=A.B or X=(A.B)' ADD LOGIC GATE IMAGE FROM BOOK |
| Truth table of a NAND gate? | TABLE FROM BOOK |
| What is a NOR gate? | X will always be 0 unless A and B are 0. Statement for NOR gate: X=A+B. ADD LOGIC GATE IMAGE FROM BOOK. |
| Truth table of NOR gate? | TABLE FROM BOOK |
| What is a XOR (EOR) gate? | X will always be 1 if inputs A and B are different. Statement for XOR (EOR) gate: X=A⊕B. ADD LOGIC GATE IMAGE FROM THE BOOK |
| Truth table of XOR (EOR) gate? | TABLE FROM BOOK. |
| What is a logic circuit? What does it control? | A logic circuit is an electronic circuit that combines a number of logic gates. The gates in the logic circuit will control the flow of the electricity through the circuit. |
