What are the 5 types of transmission modes?

Question

I need to know this by tommorow, any answers would be appreciated thanks!!

Answer 1

The five types of transmission modes are Simplex, half-duplex and full-duplex connections, Serial and parallel transmission, Synchronous and asynchronous transmission. A simplex connection is a connection in which the data flows in only one direction, from the transmitter to the receiver. This type of connection is useful if the data do not need to flow in both directions. A half-duplex connection (sometimes called an alternating connection or semi-duplex) is a connection in which the data flows in one direction or the other, but not both at the same time. With this type of connection, each end of the connection transmits in turn. This type of connection makes it possible to have bidirectional communications using the full capacity of the line. A full-duplex connection is a connection in which the data flow in both directions simultaneously. Each end of the line can thus transmit and receive at the same time, which means that the bandwidth is divided in two for each direction of data transmission if the same transmission medium is used for both directions of transmission.
