  Re: 7. What are tri-state devices and why they are essential in a bus oriented system?
Answer
# 1
In a multiplexed bus system, many devices are connected to 
a common bus. If 2 or more devices attempt to use the bus 
at the same time , then data will be lost. Thus only one 
one device must be allowed to use the bus at a time. O e 
method is to connect the devices through tri-state 
devices , which when disabled will effectively discoonect 
devices from the bus.
