I stumbled across this nice summary of common communication protocols on the Network Tutorials website.
It’s a good refresher read for those of you in the know…. And it’s a good overview for those of you who want to know.
A few protocols of interest to me from this article are: HTTP, POP3, SMTP, IMAP and of course FTP. Definitely taught me a few things…. Too bad that SSH (my recommended protocol for encrypted secure file transfer) is only listed as “other”, but overall a good quick cheat sheet of communication protocols.
