Which data communication method is used to transmit the data over a serial communication link
Half-duplex and Full-duplex data communication method is used to transmit the data over a serial communication link.
Full-duplex method is used to transmit the data over a serial communication link. Two wires needed to send data over a serial communication link layer. ... Both the connected devices can transmit and receive at the same time. Therefore it represents truly bi-directional system.
Half-duplex data transmission means that data can be transmitted in both directions on a signal carrier, but not at the same time. For example, on a local area network using a technology that has half-duplex transmission, one workstation can send data on the line and then immediately receive data on the line from the same direction in which data was just transmitted. Like full-duplex transmission, half-duplex transmission implies a bidirectional line (one that can carry data in both directions).
Simultaneous two-way data or voice transmission. A telephone conversation is full-duplex (both parties, if they so wish, may talk at the same time and be heard), but a walkie talkie conversation is half-duplex (one talks, the other listens).Refers to the transmission of data in two directions simultaneously. For example, a telephone is a full-duplex device because both parties can talk at once. In contrast, a walkie-talkie is a half-duplex device because only one party can transmit at a time.
