Digital Logic circuitry has how many states?

Digital logic circuitry operates primarily in two states, commonly referred to as binary states: high (often represented as 1) and low (represented as 0). This binary nature is fundamental to digital electronics, allowing for the representation of data and the execution of logical operations using binary digits (bits).

The two states correspond to the basic elements of digital circuits, such as transistors, which can either be in an "on" (conducting) or "off" (non-conducting) position. This dual-state system enables the construction of various logic gates (AND, OR, NOT, NAND, NOR, etc.) that form the basis for more complex digital systems, including computers.

While certain digital systems can represent more than two states in specialized applications (such as multivalued logic or quantum computing), traditional digital logic as utilized in standard circuits adheres to this binary framework, thus confirming that the number of states in digital logic circuitry is indeed two.
