twoway data transfers Half duplex is twoway communication, with each end of the system taking turns transmitting Full duplex is twoway communication that occurs simultaneously
In all interactions between a host computer (such as an information service or a BBS) and a user on a terminal or computer with communications software, the state of the duplex parameter defines whether or not the host computer sends back the characters the user types in In full duplex (echo on), the host will send back every character the user types in In half duplex (echo off), the host will not send back the characters, and the user's local computer or terminal writes each character to the screen directly If your communication software or terminal is set to full duplex, and your host is set to half duplex, nothing you type will appear on your screen If your communications software is set to half duplex, and your host is set to full duplex, everything you type will come back doubled on your screen, lliikkee tthhiiss Full duplex makes it easier to ensure that what you host receives is exactly what you typed, but takes up more bandwidth
Duplex equipment provides two, usually identical, IT components each of which is capable of performing the full task if the other fails Full duplex line/ channel allows simultaneous transmission in both directions Half duplex/ channel is capable of transmitting in both directions, but only one direction at a time
allowing communication in opposite directions simultaneously; "duplex system"; "duplex telephony" (used technically of a device or process) having two parts; "a duplex transaction
In serial communication, if a character typed on a keyboard goes directly to the screen, duplex is said to be "half " If the character is sent to the receiving device, and echoed back (thus confirming communication), duplex is said to be "full " Full duplex is most common If a keystroke results in double characters on the screen, one device is probably set to full duplex, and the other to half
(1) A text formatting term: Printing on both sides of the paper (2) A computer communications term: Half duplex: data transmission in only one direction at a time; and Full duplex: simultaneous data transmission in both directions
1 (data communications) A circuit used to transmit signals simultaneously in both directions 2 (general) Two receptacles or jacks in a common housing which accepts 2 plugs
Simultaneous transmission in both directions, sometimes referred to as full duplex to differentiate it from half duplex, which is alternating transmission in each direction Transmission in only one direction is called simplex transmission
Full duplex line/channel allows simultaneous transmission in both directions Half duplex line/channel is capable of transmitting in both directions, but only in one direction at a time
Full duplex is data is flowing in both directions at the same time When Remote echo is ON communication is occurring in full duplex Half Duplex has data moving in only one direction at a time (Local echo is ON)
