We discuss Telnet and FTP and their secure, encrypted replacements SSH, SCP and SFTP. We then discuss Usenet’s NTTP Network News Protocol, Internet Relay Chat (IRC) and commercial Instant Messenger systems. We describe and compare file and printer networking protocols NFS (Network File System) and the Microsoft-compatible SMB. Finally, we discuss peer-to-peer file sharing and anonymity networks, including Bittorrent and Tor.
