What's a good place to learn about all the networking jargon in this article?

Also, a nitpicky point: As a community it would be nice to stop thinking of 'links to wikipedia pages, mdn docs, or github issues' as useful or pertinent forms of citations or footnotes. If I'm immersed in an article and I come across a term I don't know like 'SCTP', do you think a link to some dense proposal standard webpage is appropriate in this context for providing the background info I need?

Of course academia is guilty of this too. Canonical citations don't tell the reader much else beyond 'I know what I'm talking about' and 'if you want to know more spend 30 minutes reading this other article'

But since we're web based here I think we can do better. Tooltips that expand into a helpful paragraph about e.g. SCTP would be a start.
