===Spiegazione del funzionamento delle porte===
1. Porta AND
*L'uscita della porta AND è 1 se entrambi i suoi due ingressi sono 1; altrimenti, l'uscita sarà 0.

2. Porta OR
*L'uscita della porta OR è 1 se uno o l'altro dei suoi due ingressi sono 0; altrimenti, l'uscita sarà 0.

3. Porta NOT
*L'uscita dalla porta NOT è sempre uguale all'oposto del suo ingresso.

<tr>
<td>A</td>
<td>X</td>

<td>1</td>
</tr>
<tr>
<td>1</td>
<td>0</td>
</tr>
</table>
4. Porta NAND
*As if a NOT gate had been stuck on the end of an AND gate; i.e., if both inputs are 1, the output will be 0, else it will be 1

5. NOR Gate
*As if a NOT gate had been stuck on the end of an OR gate; i.e., if either input is 1, the output will be 0, else it will be 1
[[Image:Nor-gate-en.svg|thumb|center|128px|NOR gate]]

6. XOR gate
*This gate is identical to the OR gate except for when the inputs are the same - in this case it is 0 as well
