Explain the truth table for an OR gate.

• A | B | Output, 1 | 0 | 1, 0 | 1 | 0, 1 | 1 | 0, 1 | 1 | 1

• A | B | Output, 1 | 0 | 0, 0 | 1 | 0, 1 | 0 | 0, 1 | 1 | 0

• A | B | Output, 0 | 0 | 0, 0 | 1 | 1, 1 | 0 | 1, 1 | 1 | 1

• A | B | Output, 0 | 0 | 1, 0 | 1 | 0, 1 | 0 | 1, 1 | 1 | 0

Describe the working principle of an XOR gate.

• XOR gate is a gate that outputs 1 when both inputs are 0.

• XOR gate is a gate that outputs 0 when both inputs are 1.

• XOR gate is a digital logic gate that gives a high output (1) only when the number of true inputs is odd.

• XOR gate is a digital logic gate that gives a high output (1) only when the number of true inputs is even.

Differentiate between a half adder and a full adder.

• A half adder is used for subtraction, while a full adder is used for addition.

• A full adder adds two single-bit binary numbers.

• A half adder adds two single-bit binary numbers, while a full adder adds three single-bit binary numbers.

• A half adder adds three single-bit binary numbers.
