A comparator is a logic device used to compare two binary numbers or signals. It typically has two input terminals for the numbers to be compared and outputs a logical indication of their relationship, such as equality, greater than, or less than. The output is determined based on the comparison of corresponding bits of the input numbers. In essence, it examines whether one input is greater than, less than, or equal to the other. Comparators are widely used in digital circuits, such as in arithmetic and logic units (ALUs), in microprocessors, and in data processing applications. They play a crucial role in tasks such as sorting, decision-making, and controlling the flow of data in electronic systems.
