Editing Software bug (section)

=== Interfacing ===
* Incorrect API usage.
* Incorrect protocol implementation.
* Incorrect hardware handling.
* Incorrect assumptions of a particular platform.
* [[Software incompatibility|Incompatible]] systems. A new [[API]] or [[communications protocol]] may seem to work when two systems use different versions, but errors may occur when a function or feature implemented in one version is changed or missing in another. In production systems which must run continually, shutting down the entire system for a major update may not be possible, such as in the telecommunication industry<ref name="Kimbler1998">{{cite book|first=K. |last=Kimbler|title=Feature Interactions in Telecommunications and Software Systems V|url={{google books |plainurl=y |id=q7BSGKJrWxsC|page=8}}|year=1998|publisher=IOS Press|isbn=978-90-5199-431-5|page=8}}</ref> or the internet.<ref name="Rahman2001">{{cite book|last=Syed |first=Mahbubur Rahman|title=Multimedia Networking: Technology, Management and Applications: Technology, Management and Applications|url={{google books |plainurl=y |id=e3rAmuQSUXkC|page=398}}|date=2001|publisher=Idea Group Inc (IGI)|isbn=978-1-59140-005-9|page=398}}</ref><ref name="WuIrwin2016">{{cite book|first1=Chwan-Hwa (John) |last1=Wu|first2=J.

If there is the slightest incompatibly between old and new versions, chaos can result."</ref> In this case, smaller segments of a large system are upgraded individually, to minimize disruption to a large network. However, some sections could be overlooked and not upgraded, and cause compatibility errors which may be difficult to find and repair.
* Incorrect code annotations.
