show the differences between AND and OR gate by means of truth table

Sure, here are the truth tables for both the AND and OR gates:

AND Gate Truth Table:
--------------------
| A | B | Output |
--------------------
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
--------------------

OR Gate Truth Table:
--------------------
| A | B | Output |
--------------------
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
--------------------

Differences between AND and OR gates:
- AND gate gives an output of 1 only when both inputs (A and B) are 1. Otherwise, if any or both of the inputs are 0, the output will be 0.

- OR gate gives an output of 1 if at least one of the inputs (A or B) is 1. It only gives an output of 0 when both inputs are 0.

In summary, the main difference is that the AND gate requires both inputs to be 1 to produce a 1 output, while the OR gate only requires at least one input to be 1 to produce a 1 output.
