Mode Transmisi Full Duplex
Full-duplex data transmission means that data can be transmitted in both directions on a signal carrier at the same time. For example, on a local area network with a technology that has full-duplex transmission, one workstation can be sending data on the line while another workstation is receiving data.

( September 2015) A duplex is a system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment of equipment in the field. There are two types of duplex communication systems: full-duplex (FDX) and half-duplex (HDX).In a full-duplex system, both parties can communicate with each other simultaneously. An example of a full-duplex device is a; the parties at both ends of a call can speak and be heard by the other party simultaneously. The earphone reproduces the speech of the remote party as the microphone transmits the speech of the local party, because there is a two-way communication channel between them, or more strictly speaking, because there are two communication channels between them.In a half-duplex system, both parties can communicate with each other, but not simultaneously; the communication is one direction at a time.
An example of a half-duplex device is a two-way radio that has a ' button; when the local user wants to speak to the remote person they push this button, which turns on the transmitter but turns off the receiver, so they cannot hear the remote person. To listen to the other person they release the button, which turns on the receiver but turns off the transmitter.Systems that do not need the duplex capability may instead use, in which one device transmits and the others can only 'listen'. Examples are radio and television,. In these devices the communication is only in one direction. A simple illustration of a half-duplex communication systemA half-duplex (HDX) system provides communication in both directions, but only one direction at a time (not simultaneously). Typically, once a party begins receiving a signal, it must wait for the transmitter to stop transmitting, before replying.An example of a half-duplex system is a two-party system such as a, wherein one must use 'over' or another previously designated keyword to indicate the end of transmission, and ensure that only one party transmits at a time, because both parties transmit and receive on the same frequency. A good analogy for a half-duplex system would be a one-lane road with traffic controllers at each end, such as a two-lane bridge under re-construction.
Traffic can flow in both directions, but only one direction at a time, regulated by the traffic controllers.Half-duplex systems are usually used to conserve, since only a single is needed, which is shared alternately between the two directions. For example, a walkie-talkie requires only a single for bidirectional communication, while a, which is a full-duplex device, requires two frequencies to carry the two simultaneous voice channels, one in each direction.In automatically run communications systems, such as two-way data-links, the time allocations for communications in a half-duplex system can be firmly controlled by the hardware.

Thus, there is no waste of the channel for switching. For example, station A on one end of the data link could be allowed to transmit for exactly one second, then station B on the other end could be allowed to transmit for exactly one second, and then the cycle repeats.In half-duplex systems, if more than one party transmits at the same time, a occurs, resulting in lost messages.Full duplex. A simple illustration of a full-duplex communication system. Full-duplex is not common in handheld radios as shown here due to the cost and complexity of common duplexing methods, but is used in, and.A full-duplex (FDX) system, or sometimes called double-duplex, allows communication in both directions, and, unlike half-duplex, allows this to happen simultaneously. Land-line networks are full-duplex, since they allow both callers to speak and be heard at the same time, with the transition from four to two wires being achieved by a in a. Modern are also full-duplex.A good analogy for a full-duplex system is a two-lane road with one lane for each direction.

Moreover, in most full-duplex mode systems carrying computer data, transmitted data does not appear to be sent until it has been received and an acknowledgment is sent back by the other party. In this way, such systems implement reliable transmission methods.Two-way radios can be designed as full-duplex systems, transmitting on one frequency and receiving on another; this is also called frequency-division duplex.
Frequency-division duplex systems can extend their range by using sets of simple repeater stations because the communications transmitted on any single frequency always travel in the same direction.connections work by making simultaneous use of two physical inside the same jacket, which are directly connected to each networked device: one pair is for receiving packets, while the other pair is for sending packets. This effectively makes the cable itself a collision-free environment and doubles the maximum total transmission capacity supported by each Ethernet connection.Full-duplex has also several benefits over the use of half-duplex. First, there are no collisions so time is not wasted by having to retransmit frames. Second, full transmission capacity is available in both directions because the send and receive functions are separate.
