When referencing network topologies, what distinguishes half$-$duplex from full$-$duplex communication in a point$-$to$-$point link?

Half$-$duplex communication uses a single cable for data transmission, whereas full$-$duplex requires separate cables for each direction.

Full$-$duplex communication is limited to one direction at a time, similar to half$-$duplex, but it operates at higher speeds.

Half$-$duplex allows for data transmission in both directions, but not simultaneously; full$-$duplex phrmits simultaneous two$-$way data transmission.

Half$-$duplex communication can only occur in one direction, while full$-$duplex allows for data transmission in both directions but not at the same time.
