A structured, comprehensive reference of core networking concepts and diagrams — curated, organized, and refined for real-world clarity.
A curated collection of networking fundamentals, organized to simplify concepts, reinforce understanding, and serve as a reliable reference. This includes material from books, coursework, and practical exploration — distilled into clean, navigable markdowns.
- Content is structured for fast lookup and revision.
- Concepts are broken down for clarity and retention.
- Diagrams support visual understanding
It’s not a formal course — it’s a public knowledge vault.
- Basics & Concepts: What networks are, how they talk, and why it matters
- Devices & Topologies: NICs, switches, routers, hubs, APs, star/bus/ring/mesh
- Transmission Media: Ethernet, coax, fiber, WiFi, radio, satellite
- Addressing & Identity: IPv4/IPv6, subnets, NAT, MACs, ports, hostnames
- Protocols & Reference Models: OSI, TCP/IP, ARP, DNS, HTTP/HTTPS, TLS, TCP/UDP
- Security Concepts: VPN, TOR, proxies, reverse proxies
📌 Note: This repo doesn’t cover everything (yet).
I’ll continue adding more topics and diagrams as time unfolds.
