A form of 2-way communication that allows users to receive and communicate by voice, but not at the same time. Half duplex is common in speakerphones, intercoms, and 2-way radios.
Transmissions [communications] which occur in only one direction at a time, but that direction can change.
The communication mode in which a device is capable of either sending or receiving, but not simultaneously.
Capability for data transmission in only one direction at a time between a sending station and a receiving station. Compare with full duplex and simplex.
Refers to the transmission of data in just one direction at a time. For example, a walkie-talkie is a half-duplex device because only one party can talk at a time. In contrast, a telephone is a full-duplex device because both parties can talk simultaneously. Most modems contain a switch that lets you select between half-duplex and full-duplex modes. The correct choice depends on which program you are using to transmit data through the modem. In half-duplex mode, each character transmitted is immediately displayed on your screen. (For this reason, it is sometimes called local echo characters are echoed by the local device). In full-duplex mode, transmitted data is not displayed on your monitor until it has been received and returned (remotely echoed) by the other device.
hands free: conversation is only possible in one direction at once. Whichever party is speaking cuts off the other party.
The transmission of data between two terminals in only one direction at any given time. (Transmission may be in both directions but not at the same time.)
Simultaneous send and receive of data but at different speeds, more information ...
When in a two system setup only one system can send or receive at one time.
This is a circuit capable of transmitting data in both directions but not simultaneously.
A telecommunications system where data can only flow in one direction at a time. Cheaper speakerphones are a good example of this, where only one person can talk at a time.
One-way-at-a-time communications between two devices.
A circuit designed for transmission alternately in either direction but not in both directions simultaneously. Contrast with Full Duplex.
Communications in both directions (transmit and receive), but in only one direction at a given instant in time.
The process whereby a device can receive or transmit but never do both at the same time.
Alternating the direction of transmission of signals between two terminals or computers but not transmitting in both directions simultaneously. Contrast with duplex.
Single way transmission. Is capable of both Transmitting and Receiving but not simultaneously
A transmission mode that supports transmission in two directions, but in only one direction at a time.
Alternating transmissions; each station can either transmit or receive, not both simultaneously. Describes the condition when a terminal displays its own transmissions instead of a remote end echo. A configuration option in some modems allowing local character echo.
Data transmission that can occur in two directions over a single line, but only one direction at a time.
A mode of data transmission in which each device alternately receives and transmits data.
Communications in two directions, but only one at a time.
is bidirectional transmission in alternating (not simultaneous) directions.
Signal can only go in one direction at a time, ie. a device can only transmit, OR receive, not both at the same time. A two-wire current loop is half-duplex, as is RS-485, IFSF LON, Ethernet and many others. Half-duplex uses less wires (two wires can be full-duplex, but the circuits are more complex), but requires some kind of protocol to avoid conflicts. In most forecourt protocols, it simply master-slave: a master device (the Controller) transmits to a single pump, and then waits for a response from that pump. Other pumps are not supposed to transmit at the same time. IFSF and Ethernet use more complex rules so that any device can start transmitting at any time.
A signal or transmission where the transfer of data can go in both directions, however, it can only be sent in one direction at a time.
A communication method where one end transmits while the other end receives, then reverses the process.
a communication channel over which both transmission and reception are possible but only in one direction at a time.
Communication in both directions (receive and transmit), but only in one direction at a time.
Operational mode of a communication circuit in which each end can transmit and receive data, but not simultaneously.
A channel or device which can communicate in both directions, but not simultaneously.
Capability for data transmission in only one direction at a time between a sending station and a receiving station. BSC is an example of a half-duplex protocol. See also BSC.
The term half-duplex means the transmission of data in either direction but only one direction at a time.
The normal connection type of network interface cards on Ethernet set-ups. Data can only be received or transmitted at one time (not both).
A communications system that can transmit in only a single direction at a time. Half duplex is abbreviated HD. Learn more about Half Duplex...
A data communications circuit over which data can be sent in only one direction at a time.
Some sound cards only support Half Duplex. In Half Duplex audio data can travel in one direction at a time, therefore in a conversation using this type of card only one person at a time can speak and be heard.
A mode of audio or data communication that works in both directions but not at the same time.
Communication process that allows only one parties to transmit (talk) at a time.
The ability to send data in only one direction at a time.
A mode of radio operation where the transmitter and receiver operate on different frequencies, but cannot operate simultaneously (cannot talk and listen at the same time).
Signal flow in 2 directions but not simultaneously
A communications channel allowing alternating transmission in two directions, but not in both directions simultaneously.
An asynchronous communications protocol that allows one-way communication.
Alternating two-way communication path (one way at a time).
Signal flow in both directions, but only one way at a time. In microcomputer communications, may refer to activation of the online Local Echo, which causes the modem to send a copy of the transmitted data to the screen of the sending computer.
Communicating in only one direction at a time.
Communication over a bi-directional medium in which only one end may send or receive data at a time.
Operation of data communications link where transmissions are possible in both directions but only in one direction at a time.
a mode of communication in which you transmit at one time on one frequency and receive at another time on another frequency
A circuit or device capable of transmitting in two directions, but not at the same time.
Half-duplex communication means that data flow can be alternately transmitted and received across a communications channel.
Transmission in either direction, but not at the same time.
A telecommunication system where data can only flow in one direction at a time. For example, a half duplex speakerphone only allows one person to speak at a time. (Compare with Full Duplex).
Transmission systems which can send and receive, but not at the same time.
Data communications mode which permits transmission in both directions, but only in one direction at a time.
The ability either to send or to receive data at a given time.
Originally a modem communications term, half duplex now mainly...
Data transfer that only sends or receives data to a node. Hubs commonly perform in half duplex mode.
a communications channel over which data transmissions can travel in both directions, but not at the same time.
Alternating transmissions over a communications link. Each station can either transmit or receive, but cannot do both simultaneously.
Signal flow in both directions, but only one way at a time. It is sometimes used to refer to activation of LOCAL ECHO which causes a copy of sent data to be displayed on the sending display.
