Email, as far as im aware there isn’t some alternative email standard (messaging services, whatsapp, signal, sms, etc do not count imo as I believe they serve a different purpose than email)
DNS, while there are alternative root servers, they still fundamentally rely on the dns protocol.
TCP/IP, when the internet was first starting, this was not the only standard in use, but now it is (to my knowledge).
I thought about this for longer than I should’ve for a comment on a random post, but this is all I could think of lol.
edit: grammar

TCP/IP is not the same as TCP, and UDP/IP doesn’t exist

You’re saying I’m wrong?
Id consectetur dolore eiusmod culpa.
We also have I2P now.
Id consectetur dolore eiusmod culpa.
that’s a different layer, it’s not transport but a network protocol. it “competes” with IP

Ah, I shouldve been more clear. I didnt just mean tcp specifically, I meant IP as a whole, for an example of a competing standard see x.25.
Funny enough, that wikipedia article mentions that x.25 is still in use by the aviation industry, and after a quick search it seems it is! So I guess Im still wrong lol.

You can probably throw Ethernet in there as well then, unless there’s anyone out there rocking a Lemmy instance on token ring…
USB has worked pretty well IMO
My main complaint about USB is the cables. There’s no way of knowing what standards and data speeds the cable may support.
