• What is meant by a bus?
A bus is a group of conducting lines that carriers data, address, & control signals.
• What is Tri-state logic?
Three Logic Levels are used and they are High, Low, High impedance state. The high and low are normal logic levels & high impedance state is electrical open circuit conditions. Tri-state logic has a third line called enable line.
