1. What is an AND Gate?

The AND gate is a basic digital logic gate that implements logical conjunction. It outputs 1 (true) only when all of its inputs are 1, otherwise it outputs 0 (false).

2. How Does the Calculator Work?

The calculator uses the AND gate formula:

Where:

• \( a \) — First input (0 or 1)
• \( b \) — Second input (0 or 1)
• \( y \) — Output (0 or 1)

Explanation: The output is 1 only when both inputs are 1.

3. Truth Table

a	b	y
0	0	0
0	1	0
1	0	0
1	1	1

4. Using the Calculator

Tips: Select either 0 or 1 for both inputs a and b. The calculator will compute the AND operation result.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between AND and OR gates?
A: AND outputs 1 only when all inputs are 1, while OR outputs 1 when any input is 1.

Q2: Can I use this for more than 2 inputs?
A: This calculator handles 2 inputs, but AND gates can have more inputs in digital circuits.

Q3: What are real-world applications of AND gates?
A: Used in digital circuits, computer processors, and control systems where conditional operations are needed.

Q4: How does AND relate to Boolean algebra?
A: AND represents logical conjunction in Boolean algebra (∧ or · operation).

Q5: What other basic logic gates exist?
A: Other basic gates include OR, NOT, NAND, NOR, XOR, and XNOR.
