How does that establishment of terms happen?
Terminology for computer stuff is defined by a combination of multiple internationally recognized engineering organizations (e.g. IEEE, etc)*, decades of peer reviewed academic publications, ISO controlled documents and white papers from manufacturers, and media publications that are read and discussed by millions.
Meanwhile, our terminology started with a pile of purple prose from Gary Gygax and is now largely defined in blog form.
*It took every ounce of grammar nazi in me to not write this as "i.e. IEEE"
