What are the 3 data communication?
Half-duplex: Data travels in one direction (from A to B) and then the other direction (from B to A) but not at the same time.
The RS-485 is half-duplex.
Full-duplex: Data can travel in both directions at the same time..
What are the 5 components of data communication?
Components of Data CommunicationMessage: The message is the information (data) to be communicated. … Sender: The sender is the device that sends the data message. … Receiver: The receiver is the device that receives the message. … Transmission medium: The transmission medium is the physical path by which a message travels from sender to receiver. … Protocol:
What are the three types of data transmission?
