Data Flow : Simplex & Half Duplex& Full Duplex &
Data Flow : Simplex, Half Duplex, Full Duplex What are the types of data flow? Communication between two devices can be simplex , half - duplex , or full-duplex. What is simplex communication? 1__Simplex: In simplex mode : the communication is unidirectional, as on a one-way street. Only one of the two devices on a link can transmit; the other can only receive . The simplex mode can use the entire capacity of the channel to send data in one direction . What is Half-Duplex communication? 2__Half-Duplex : In half-duplex mode : each station can both transmit and receive, but not at the same time. When one device is sending, the other can only receive, and vice versa. NOTE In a half-duplex transmission ,the entire capacity of a channel is taken over by whichever of the two devices is transmitting at the time. The half-duplex mode is used in cases where there is no need for communication in both directions at the same time; the entire c...
