The XOR gate outputs true only when inputs differ, making it a fundamental digital logic gate.
XOR stands for 'exclusive or'.
Truth table has two inputs: A and B.
Output is true (1) if A and B are different.
Output is false (0) if A and B are the same.
Example: A=0, B=0 -> Output=0; A=0, B=1 -> Output=1; A=1, B=0 -> Output=1; A=1, B=1 -> Output=0.
