Point-to-point Communication

In Point-point connections, data sent can either go one way (Simplex) or both ways (Duplex).

Simplex

There is only one-way that data can go

Half Duplex

Data can go either way, but there is only 1 stream so transmitting and receiving must take turns.

Full Duplex

There are designated transmitter and receiver endpoints. Data can be transmit and received at the same time.
