Out-of-band activity is activity outside a defined telecommunications
frequency band, or, metaphorically, outside of any primary
communication channel. Protection from
falsing is among its purposes.
Examples
General usage
Out-of-band agreement, an agreement or understanding between the communicating parties that is not included in any message sent over the channel but which is relevant for the interpretation of such messages
More broadly, communication by any channel other than the primary channel can be considered "out-of-band". For example, given a
website's primary communication method is the
internet, out-of-band communication may be an
SMS message or even
beeps produced by a
speaker on the
server itself.
Telecommunications
Out-of-band signaling, the exchange of call control information in a separate band from the data or voice stream, or on an entirely separate, dedicated channel
Computing
Out-of-band data, in computer networking, a separate stream of data from the main data stream
Out-of-band management, in computer administration, system console access, even in the event of primary network subsystem failure
Out-of-band
software documentation, documentation that is not provided together with the software it documents. This contrasts with
Unix and
Unix-like systems, for example, where software is documented through the means of on-line (meaning 'on a main computer', not 'over the internet')
man pages provided as a component of the
operating system.[1] Out-of-band documentation, whether on
web pages or in printed form, can suffer from a mismatch regarding the version and the exact set of features that are being documented.[2]
