If you couldn't make any sense of any words, you're not out of touch, just not very literate in English. There really is very little jargon and most of it could be used to describe historical situations.
And as someone else mentioned, this is really not tech.
You seem to think that "understanding" something is based only on knowledge of a language or its jargon.
In this case, ironically, I think you are confused because of your own language background. Not a criticism, but just pointing that out. Can I guess English is not your native language? I often hear people focus on language issues when language is not usually the actual issue, and usually when they are not native to the language they are talking about.
Predictably downvoted, given the wording, but my intent was not to slight anyone. I'm genuinely puzzled about what could be so impenetrable to a fluent English speaker. I'd love to hear about it for that matter.
Probably should have phrased it as a question, in retrospect -- the reason it is not is that I kind of expected that there were no good answer and that this was a "knee-jerk comments". Sort of the same kind of people who throw (sometimes literally) their hands up in the air and exclaim "I understand nothing about it" when you only mention the word "informatics" (well, the equivalent in my mother tongue).
