I worked through the sections on TCP and UDP in Computer Networking. It was interesting that, whereas the application layer protocols were mostly ASCII, the transport layer is much more densely encoded into some standardized block of bytes with a check-sum for redundancy. I'm guessing the checksum is similar to the hashes we're talking about in Algorithms.
I also looked into SSH a little more. SFTP, according to Wikipedia, is not just FTP implemented of SSH but rather a new protocol on top of SSH that can be used for the same things as FTP.
I also looked at the RFCs for SSH and TCP. I Had trouble reading them as they both seemed designed for readers with a lot more familiarity with the protocols than the one for HTTP did.
