Many fields — and the computer field is no exception — have confusing terminology. There are odd words which you have never seen before, and this can be offputting.
However, the alternative is worse. Familiar words can be reused as terminology. This can lead to confusion when you do not know that there is another definition.
For an example of the confusion, see Odd Language #85: Chat?. The original poster for the thread knew the ordinary English word “chat” as talking but not the computer meaning of a live conversation by typing. This was quite relevant, because his hearing is badly impaired.
The advantage of terminology being words that you do not know means that you know that you do not know. Knowing that one does not know is higher on the scale than thinking one knows but does not. And is less confusing, too.
