In terms of computer networks, protocols are used to provide a required set of rules that enable computers to exchange information. Well-known Internet protocols include Transmission Control Protocol/Internet Protocol, User Datagram Protocol/Internet Protocol, File Transfer Protocol, and Hypertext Transfer Protocol. Ports, by comparison, are used to identify a type of network or specific process. Port numbers, ranging from 0 to 65535, are typically divided into three categories - well-known ports, dynamic ports, and registered ports. In this course, you'll learn about the most commonly-known ports in use on a computer network today. These include File Transfer Protocol, Simple Mail Transfer Protocol, Domain Name System, and Hypertext Transfer Protocol. You'll examine how HTTP uses the reserved port 80 and enables computers to send and receive Web client-based communication and messages from a Web server, including web site pages and data. Next, you'll explore other key ports including, port 25, reserved for Simple Mail Transfer Protocol and how SMTP allows e-mail clients and services to send out e-mails. You'll learn how port 100, reserved for Post Office Protocol v3 and port 143, reserved for Internet Message Access Protocol, allow for e-mail clients to retrieve e-mail messages from a mail server over a TCP/IP connection. Lastly, you'll learn about Secure Sockets Layer and how it can be incorporated into POP3 and IMAP implementations to enable more secure encrypted e-mail communications
