Not everyone knows the exact wording to describe something. Not everyone has your pertained level of engineering experience, terminology experience etc etc etc. Please remember we do have a large number of young members on here who do not have any engineering background or mechanical knowledge.
To come across as belittling and arrogant will not help the case either. You have been told about this before and yet you choose to ignore this.
In the perfect world EVERYONE would know exactly what a Klystron Cavity Control unit is and how a Flux Capacitor works but we do not so bare that in mind when you answer someones question. Politely point them in the right direction, don't go shouting at them in CAPS LOCK, there is no need.
