Basic Ethernet technology is half-duplex.

"Full-duplex Ethernet" is a hacky thing using two Ethernet
"connections". It is strictly point-to-point. (Robert Metcalfe would roll
in his grave, except that he's still alive.)  8-)}

Configured the right way, a p-p FastEthernet can be made to run
Full-duplex. To an oldtimer like me, it is no longer Ethernet; just a
pair of baseband data adaptors with 4 wires between them. Take away them
collisions and the common channel and it's like Christianity without
Christ.

(I still have an Ethernet 1.0 adaptor in the cupboard which I show to
students. Weighs about 1kg.) 10base5 of course, except it wasn't called
that then.
