In Microprocessor based system devices are connected n parallel through the bus in this situation it is required that one device is interact with the bus at a time .If more than one device make communication wid bus then more then one signal is places that they will produce damaging current known as Bus Contention.To avoid bus contention tristate buffer are placed between buses and peripheral...
The "tristate area" of New York consists of New York, New Jersey and Connecticut.

Tri-state
A tristate device is a device that has three states instead of two. The normal states are low and high, where the output is pulled down or up by turning on one of the two output transistors. The third state is floating, where neither transistor is turned on. Tristate devices are useful in a bus design where, for instance, more than one device can drive a data bus, but only one at a time.
How does a microprocessor decode?
Tristate devices are used in bus based systems to allow multiple bus drivers to control the bus, each at different times, while all the rest are allowed to read the bus. Only one device can drive the bus at any one time. All the others "tristate" or float, so they neither drive the bus low nor high.
The plural of microprocessor is microprocessors.
Microprocessor is a single chip processor.
The microprocessor is a piece of hardware, not software. Windows 7 doesn't supply a microprocessor.
Sputnik did not use a microprocessor.
How do you interface a clock and microprocessor?
