What is the main difference between point-to-point communication and multipoint communication?
Multipoint communication is unidirectional.
Point-to-point has one transmitter and one receiver.
Multipoint has a dedicated link between two nodes.
Point-to-point has multiple transmitters.
Which mode allows both devices to transmit and receive at the same time?
Unidirectional Mode
Full-Duplex Mode
Half-Duplex Mode
Simplex Mode
