Don't really know what you're asking for here, as that's not a generally acknowledged name. There are freecoaster hubs, which are recognized by that they can be rolled backwards w/o the pedals moving along.
Transformers are inherently bidirectional.
Relays are bidirectional devices.
Data flow is always bidirectional my friend, don't confuse.
Port 0 is called true bidirectional port.............. swapneel
Bidirectional Reflectance Distribution Function
Bidirestional
Yes. The direction does not matter.
Its not, a diode is unidirectional.
Ring Network Topology
In electronics, bidirectional device is device which can be used by both directions like resistor. It does not effect on characteristics of device if we change the terminals of that device.
A data should be either WRITTEN to a memory or should be READ from a memory (both direction)and so the data bus is bidirectional.
A DS3 can do 45Mbps Bidirectional Simultaneously.
