[[File:tri-state buffer gate (ansi).svg|100px]] A '''Tri-state Buffer''' is a gate that outputs the very same input it is given only when the control signal allows it. When the control signal is off, the output is at [[high impedance]]. This gate forms the basis for [[buses]], by controlling which devices is allow to generate output to a shared [[bus]]. | [[File:tri-state buffer gate (ansi).svg|100px]] A '''Tri-state Buffer''' is a gate that outputs the very same input it is given only when the control signal allows it.

[[File:and gate (ansi).svg|100px]] An '''AND gate''' outputs a HIGH only when both inputs are HIGH, otherwise it outputs a LOW. The Boolean AND operation is equivalent to the Boolean multiplication operation. | [[File:and gate (ansi).svg|100px]] An '''AND gate''' outputs a HIGH only when both inputs are HIGH, otherwise it outputs a LOW.
