TCP/IP has four layers. The Application Layer contains user-facing protocols like HTTP (web pages), SMTP/POP3/IMAP (email), FTP (file transfer), Telnet (remote login), and SSL/TLS (secure communication). The Transport Layer acknowledges and sequences packets. The Internet Layer addresses, packages, and routes messages. The Network Interface Layer places packets on and receives them from the network medium.
