The Xor Gate, also known as the Exclusive OR Gate, is a vital component in digital electronics. This gate has many synonyms due to its importance in electronic engineering, such as "XNOR Gate," "Exclusive NOR Gate," "Equivalence Gate," "Inequality Gate," "Antivalence Gate," and "Antiequivalence Gate." All of these terms refer to the gate's function, which is to output a high level only if the inputs are different. This means that if inputs A and B are equal, the output will be low. Maintaining an understanding of these synonyms is essential for anyone working with digital electronics and programming, as they may be used interchangeably in different contexts.
