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. One
method is to connect the devices through tri-state
devices , which when disabled will effectively disconnect
devices from the bus.

What is a tristate devices?
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 tristate occurs in a microcontroller?
Tristate in a microcontroller occurs when a pin is configured to operate in a high-impedance state, effectively disconnecting it from the circuit. This is typically achieved by configuring the pin as an input or by setting it to a special mode that allows it to neither drive a high nor a low signal. This state is useful for preventing bus contention when multiple devices share the same communication lines, allowing only one device to drive the line at any given time. In this way, tristate control is essential for managing data flow in multi-device environments.
What are three factors that determine the amount of electrical energy?
The power rating of the electrical device or system. The duration for which the device or system is in use. The efficiency of the device or system in converting electrical energy into useful work.
Which device useful in monitering the cyclones?
anemometer
Conveys meaning and is useful to people?
output device
What device is not useful for measuring radiation?
For example a thermometer.
The amount of power derived from a device or system is its?
That amount is always less than the energy you put into the system. Divide the amount of useful energy you get from a system by the amount of energy you put into it, and you find the system's 'efficiency'.
A sorting device that is useful in classifying by observation is a .?
taxonomy key
What is the input device useful for playing games?
game controller
What is the efficiency of a device that gives you 100 units of useful energy for every 100 units you put in it?
The efficiency of the device is 100%. This means that all the energy input into the device is converted into useful energy output without any loss.
