TRANSMISSION METHODS SIMPLEX DUPLEX HALF FULL

SIMPLEX ALLOWS DATA TO TRAVEL ONLY IN A SINGLE, PRE SPECIFIED DIRECTION. EXAMPLES ARE TELEVISION AND RADIO BROADCASTING.

DUPLEX A duplex communication system is a system composed of two connected parties or devices that can communicate with one another in both directions. TYPES a] HALF DUPLEX b] FULL DUPLEX

HALF DUPLEX A half-duplex system provides for communication in both directions, but only one direction at a time (not simultaneously). An example of a half-duplex system is a two-party system such as a "walkie-talkie" style two-way radio,

FULL DUPLEX A full-duplex, or sometimes double-duplex system, allows communication in both directions, and, unlike half -duplex, allows this to happen simultaneously. Examples: Telephone, Mobile Phone, etc.
