I don't know what Tcp-ip stands for.
But usually, initials in Portuguese, changing to English, the order switches... Sooo lol

TCP-IP: TCP/IP Transmission Control Protocol/Internet Protocol. It’s basically how computers communicate over the internet and other networks
they are separate layers
IP is very simple
source address to receiving address, mail can and will get lost or arrive in a different order, and everyone keeps a table like “IP’s starting with 1.2 are here”
TCP fixes the fact that data can be lost by adding a sequence number to each message and waiting for a “I got it” message
if 2 comes before 1, you wait for and read 1 and only then read 2
if you send 1 but never get an answer you resend it
Yes and it's all a big mistake. The inventor of TCP, Van Jacobson, explains how it all went wrong: https://youtu.be/gqGEMQveoqg
