why they are essential in a bus oriented system?

Ans) In a multiplexed bus system, many devices are linked to a common bus. If 2 or more devices attempt to use the bus at the similar time, then data will be lost. Therefore only one single device must be permitted to use the bus at a time. The method is to join the devices by tri-state devices , which when disabled will effectively disconnect devices from the bus.
