Hi guys,
Because simplex can run in only one direction it needs only 1 wire.
Does it use coaxial cable for example ?
Because half - duplex can run in both directions but not at the same time it requires 2 wires.
If it is not used at the same time, why not 1 wire also ?
Full - duplex runs in both directions at the same time.
Why then it uses 4 wires instead of 2 ?
Thanks in advance.
