Answer
A truth table is a mathematical table used to represent the possible outcomes of a logical expression based on all possible combinations of its inputs. It is commonly used in Boolean algebra and digital logic design to visualise how the logical operations like AND, OR, NOT, etc. will behave with different input values.
For example, the truth table of AND operator is shown below:
| A | B | A AND B |
|---|---|---|
| True | True | True |
| True | False | False |
| False | True | False |
| False | False | False |
In this table, A AND B is true only when both A and B are true.
