A two input XOR Gate produces a high output only when its both inputs are:(A) same(B) different (C) low(D) high

The correct answer is: (B) different
An XOR (Exclusive OR) Gate is a digital logic gate that outputs a HIGH (1) signal only when the two inputs are different. It is called "exclusive OR" because it excludes the case where both inputs are HIGH.
Truth Table for XOR Gate:
Input A Input B Output (A ⊕ B)
0 0 0
0 1 1
1 0 1
1 1 0
• When both inputs are the same (both LOW or both HIGH), the output is LOW (0).
• When the inputs are different (one LOW and one HIGH), the output is HIGH (1).
Logic Expression for XOR Gate:
The output YY of an XOR gate can be expressed as:
Y=A⋅B‾+A‾⋅BY = A \cdot \overline{B} + \overline{A} \cdot B
This means the output is HIGH when either AA is HIGH and BB is LOW, or AA is LOW and BB is HIGH.
Conclusion:
The XOR gate produces a HIGH output only when its inputs are different.
