Explore the OSI and TCP/IP Models

The OSI and TCP/IP models have shaped how the internet functions, so this is our starting point. What are these models? How do they compare to one another? What should you know about them? These are questions we answer as we get started in the course.

Learn about the physical layer

How are we able to communicate with people across different continents? How does wifi work? How do wired networks work? Let’s take a look!

Learn about the data link layer

MAC addresses, MAC Address Tables, switches, and Broadcast Domains, are all critical components to making networks work.

Learn about the network layer

In this section, we cover:

  1. IP addressing
  2. Routers and Routing Tables
  3. Network Masks
  4. Network and Host IDs
  5. Default Gateways
  6. Reserved, Public, and Private IPs
  7. IPv6 vs IPv4
  8. Network Address Translation (NATs)
