Question

Define Truth Table.

Hint:

Truth tables are commonly used to represent logical operations such as AND, OR, NOT, NAND, NOR, XOR, and XNOR.

Answer 1

Step 1: Understand the concept of logic in computing. 

In computer science and digital electronics, logical operations such as AND, OR, and NOT are used to evaluate conditions. These operations work with binary values such as 

True and False 

or 

1 and 0 

Step 2: Define a truth table.

A truth table is a systematic representation of all possible combinations of inputs and their corresponding output values for a logical expression or logical operation.

It helps in understanding how logical operators behave under different input conditions.

Step 3: Example of a truth table.

For example, the truth table for the logical AND operation is:

 

A	B	A AND B
0	0	0
0	1	0
1	0	0
1	1	1

This table shows the result of the AND operation for all possible combinations of inputs.

Step 4: Conclusion.

Thus a truth table helps represent logical relationships clearly and is widely used in computer science and digital circuit design.
