In which form is data communicated?

Data communication between different devices are broadly categorised into 3 types: Simplex communication, Half- duplex communication, and Full-duplex communication. It is a one way or unidirectional communication between two devices in which one device is sender and other one is receiver.

What is meant by data communication?

Data communications are the exchange of data between two devices via some form of transmission medium such as a wire cable. For data communications to occur, the communicating devices must be part of a communication system made up of a combination of hardware (physical equipment) and software (programs).

What is data communication and what is needed for communication?

Data communication usually requires the existence of a transportation or communication medium between the nodes wanting to communicate with each other, such as copper wire, fiber optic cables, or wireless signals.

What are the 3 data communication?

There are three modes of transmission, namely: simplex, half duplex, and full duplex. The transmission mode defines the direction of signal flow between two connected devices.

What are the examples of data communication?
