In [[engineering]], '''master–slave''' is a relationship between two systems in which one controls the other. In some cases one master controls just one slave system, but in others there are multiple slave systems controlled by the same master. Sometimes the master is a different kind of system than the slave, but sometimes there are multiple similar systems and one of them is designated the master in order to centralize external (i.e. user) control of the collection.<ref>{{Cite web|url=https://www.theserverside.com/opinion/Master-slave-terminology-alternatives-you-can-use-right-now|title=Master–slave terminology alternatives you can use right now|website=TheServerSide.com}}</ref>

Due to its connection to [[slavery]], the terminology is a subject of controversy and has been replaced with alternative terms in some cases.<ref>{{Cite web|last=Ellis|first=Leonard|date=2020-06-18|title=It's Time for IEEE to Retire 'Master / Slave'|url=https://www.eetimes.com/its-time-for-ieee-to-retire-master-slave/|access-date=2020-09-26|website=[[EE Times]]}}</ref><ref name="Wired">{{Cite magazine |title=Tech Confronts Its Use of the Labels 'Master' and 'Slave' |url=https://www.wired.com/story/tech-confronts-use-labels-master-slave/ |magazine=Wired |language=en-us |issn=1059-1028 |access-date=2020-07-14}}</ref><ref name="vice.com">{{Cite web |date=September 13, 2018 |title='Master/Slave' Terminology Was Removed from Python Programming Language |url=https://www.vice.com/en/article/masterslave-terminology-was-removed-from-python-programming-language/ |access-date=2020-07-14 |website=[[Vice.com]] |language=en}}</ref>
