What does a truth table describe?

A truth table provides a concise way to understand the behavior of a logic gate by outlining the outputs based on all possible input combinations. Each entry in the truth table corresponds to a specific combination of input values, indicating what the resulting output will be for that combination. This is particularly relevant in digital electronics, where logic gates (like AND, OR, NOT) operate based on binary input values (0 and 1).

The truth table displays how these gates respond to different inputs, helping engineers and technicians predict circuit behavior without needing to physically prototype or test the circuit. It serves as a foundational tool in designing and analyzing digital circuits, illustrating how logical operations are performed in a structured format.

Understanding the behavior of logic gates is crucial for anyone working in electronics, particularly in fields such as computer engineering, where logic circuits form the basis of computational processes.
