If you want to understand the basics, there is any number of tutorials
on the web. If you want to play with them, then pick a language and go
to a web page like https://docs.python.org/3/library/index.html
and write some toy programs. Most of these facilities have wrappers
that save you having to write C code to create, say, a couple of
sockets that talk to each other. If you try this in C and it doesn't
work, it might take you half a day to decide whether you've
misunderstood the socket concept or just made a programming error.
