Network Protocols - ARP, FTP, SMTP, HTTP, SSL, TLS, HTTPS, DNS, DHCP - Networking Fundamentals - L6

This video is about networking protocols. It starts by defining a protocol as a set of rules and messages that form an internet standard. The video then discusses some of the most important protocols, including ARP, FTP, SMTP, HTTP, SSL, TLS, HTTPS, DNS, and DHCP. It also explains the four things that every host needs in order to achieve internet connectivity: an IP address, a subnet mask, a default gateway, and a DNS server. Finally, the video discusses the role of DHCP in automatically configuring these settings for devices.
