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 isnt the only standard in use even today. UDP/IP is the other big one and there's a few smaller protocols hanging around like utp.
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…
I remember token ring settings in our family Mac in the early 90s. We eventually got broadband and my carpenter dad wired the house for Ethernet in around 98. He was cool dad at the time and way more tech savvy than anyone expected.
ARCnet forever!
Ipv4 vs ipv6 🫠
fair enough!
TCP/IP is not the same as TCP, and UDP/IP doesn't exist
Wat.
Lol. Dont waste peoples time in the future thanks!
You're saying I'm wrong?
Yes. UDP relies on the IP protocols just as TCP does.
as I said stop wasting peoples time. troll elsewhere.
We also have I2P now.
that's a different layer, it's not transport but a network protocol. it "competes" with IP
Dont think we need to make that distinction here. :) correct of course but ip vs i2p, tcp vs udp vs utp, etc are all different layers of the same domain.
!! i was not aware of I2P. what a wonderful network.
