In computer
telecommunications, echo is the display or return of sent data at or to the
sending end of a transmission. Echo can be either local echo, where the sending
device itself displays the sent data, or remote echo, where the receiving
device returns the sent data that it receives to the sender (which is of course
simply no local echo from the point of view of the sending device itself). That
latter, when used as a form of error detection to determine that data received
at the remote end of a communications line are the same as data sent, is also
known as echoplex, echo check, or loop check. When two modems are communicating
in echoplex mode, for example, the remote modem echoes whatever it receives
from the local modem.
Terminals are one of the
things that may perform echoing for a connection. Others include modems, some
form of intervening communications processor, or even the host system
itself.[8] For several common computer operating systems, it is the host system
itself that performs the echoing, if appropriate (which it isn't for, say,
entry of a user password when a terminal first connects and a user is prompted
to log in). On OpenVMS, for example, echoing is performed as necessary by the
host system.
