TCP/IP Fundamentals Complete Course - Beginner to Advanced

Organised as six modules

This TCP/IP course is organised into six modules that move from overview and history to application-layer protocols. The first module lays out networking fundamentals, the OSI reference model and the TCP/IP architecture.

From lower layers to transport

The middle modules cover the point-to-point protocol, address resolution, IPv4 and IPv6, and the support and routing protocols that keep IP working. The transport module then covers TCP and UDP before the application-layer survey closes the course.

Using the module structure

• Treat each module as a checkpoint before starting the next.
• Revisit IPv4 after the address resolution lessons, since the two topics are closely linked.
• Use the application-layer survey as a map for the protocols you meet at work.
