According to 7 Layers of the OSI Model, IP is located at layer 3 (Network), while TCP and UDP are located on layer 4 (Transport).
Just for the sake of curiosity, why the combination of "TCP/IP" term is more popular than "UDP/IP"?
I've been searching on internet about this, however the only site that uses UDP/IP term is http://searchmicroservices.techtarget.com/definition/UDP-User-Datagram-Protocol
Both UDP and TCP run on top of the Internet Protocol (IP) and are sometimes referred to as UDP/IP or TCP/IP.
Btw, I'm not talking about the difference between TCP vs UDP and why TCP is more popular instead of UDP.
I'm just curious why the combination of "TCP/IP" term is more popular than "UDP/IP"?
It's common to hear about "TCP/IP" term but not "UDP/IP" term right? Any idea why?
