Understanding Key Networking Protocols: ARP, FTP, SMTP, HTTP, SSL, TLS, HTTPS, DNS, DHCP

In this video we provide a formal definition for Network "Protocols". We then briefly describe the functionality of the 8 most common networking protocols on the Internet: DNS, DHCP, HTTP, SSL, TLS, HTTPS, FTP, and SMTP. We follow that with a discussion on the four items which MUST be configured to achieve any sort of Internet connectivity.

This is Lesson 6 of Module 1 of a Networking Fundamentals course. The first module will be released for free on Youtube and will teach anyone the very core of networking: How data moves through the Internet.
