What information do truth tables provide?

Truth tables provide a systematic way to represent the output of a logic gate or circuit based on its various input combinations. Each possible set of inputs is listed, along with the corresponding output, which helps to visualize and understand how the logic gate processes those inputs.

In digital electronics, logic gates like AND, OR, and NOT operate in specific ways depending on their inputs; truth tables clearly outline these relationships. For example, an AND gate will produce a high output (1) only when all its inputs are high (1), while an OR gate will output high if any of its inputs are high. This essential function of mapping inputs to outputs is critical in designing and analyzing digital circuits, making it a fundamental tool for anyone studying or working in the field of IT support and hardware.

The other choices do not accurately reflect the primary purpose of truth tables. For instance, while power consumption, voltage levels, and speed can be properties of logic gates, they are not directly represented in truth tables. Truth tables are solely focused on inputs and outputs, making option C the most appropriate answer.
