Computer Networking Roadmap
A step-by-step path through networking: foundations and models, the lower layers (Ethernet, IP, routing), transport and core services (TCP/UDP, DNS, DHCP), the application layer and the web (HTTP, TLS), and operations and security.
concepts mastered
Foundations
0% · 0/10What a network is, the models we use to reason about it, and how data actually travels
The Lower Layers
0% · 0/11Layers 1 to 3: signals and Ethernet, IP addressing and subnets, and how routers move packets
Transport and Core Services
0% · 0/9TCP and UDP, the DNS that names the Internet, and how devices get their addresses with DHCP
Application Layer and the Web
0% · 0/10HTTP and HTTPS, the TLS and PKI that secure them, and the other protocols that power email, files and real-time apps
Operations and Security
0% · 0/9The tools to diagnose networks, the defences that protect them, and the techniques that make them fast at scale
