Q: How can a telephone facilitate communication?
- Full duplex
- Twisted
- Half Duplex
- Simplex
Explanation: The term “full-duplex” refers to the kind of communication that is generally used by telephones. Full-duplex communication enables both the caller and the receiver to speak and listen simultaneously, simulating the flow of a real conversation between the two parties. In “half-duplex” communication, on the other hand, communication may go both ways, but not at the same time. This contrasts with “full-duplex” communication. Participants in a system using half-duplex communication take turns sending and receiving information. Full-duplex communication, which is used in telephones, makes it possible to have discussions that are more natural and participatory.
