What is AND Gate?
The AND Gate performs logical multiplication function. AND Gate can have many inputs and a single output. AND Gate can be represented by the figures shown below;
| Inputs | Output | |
| X | Y | Z |
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
What is NAND Gate?
The NAND Gate performs a combination of an AND gate and a NOT gate.
A NAND Gate can have multiple inputs and a single output.
| Input | Output | |
| X | Y | Z |
| 0 | 0 | 1 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 0 |
