A person who is in charge of creating, managing, and maintaining a website.
The webmaster updated the site to improve its performance and user experience.
Webmaster → It is formed from "web" (from Old English *webb*, meaning a woven fabric or network) and "master" (from Old French *maistre*, meaning one who has control or authority). The word "webmaster" refers to a person who has control or authority over a website or web-related tasks.
Think of someone who has 'control' ('master') over a 'network' ('web') of information — that's what a webmaster does.
