The Internet is built on a hierarchy of connected devices like servers, routers, switches, hubs, and many more connected devices. These devices talk to each other using protocols that are well defined and allow for new devices to be added to the network. We want to understand how these networks communicate and the protocols that they use.
Explore the protocols and systems that are used in networks that allow for communication between devices.
Students will be able to:
Describe what ports are and identify which ports are used for common protocols
Use basic web services like DNS lookup, WHOIS, and other network tools.
