What chart illustrates all possible input and corresponding output combinations for logic devices?

A truth table is a systematic way to represent the relationship between the inputs and outputs of a logic device, detailing every possible combination of the inputs and the corresponding output for each combination. It provides a complete and clear visualization of how a logic function operates, which is essential for understanding and designing digital circuits. Each row of the truth table represents a unique input configuration, while the associated output indicates the result of that configuration according to the logic function being analyzed.

The other options, like a logic diagram, represent the physical arrangement of the components in a circuit without explicitly showing the input-output relationships in a comprehensive manner. A feedback loop pertains to a situation in which output is fed back into the system as input, which is a concept rather than a representation of input-output combinations. Lastly, a circuit model describes how components are interconnected and can simulate logic operations but does not explicitly list all possible input and output pairs in a clear format like a truth table does.
