A curated set of networking concepts and diagrams, built from multiple sources.
Organized for easy learning, reference, and exploration.
This is a curated collection of networking material, built to document concepts, diagrams, and practical insights from multiple sources — including college teachings, books, and my own exploration.
- Content is organized to clarify and reinforce understanding.
- Concepts are structured for easy reference and gradual exploration.
- The material reflects real learning and synthesis, combining multiple perspectives into one resource.
It’s not a formal course, but it’s public and shareable, so anyone can browse, reference, and learn from it.
- 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: Wired (Ethernet, coax, fiber) & Wireless (WiFi, Bluetooth, radio, satellite)
- Addressing & Identity: IPs, subnets, NAT, MACs, ports, hostnames
- Protocols & Reference Models: OSI layers, TCP/IP, ARP, DNS, HTTP/HTTPS, TCP/UDP, TLS/SSL
- Security Concepts: VPNs, TOR, proxies, reverse proxies
…and all the little notes that make me go “ohhhh, now I get it.”
📌 Note: This repo doesn’t cover everything (yet).
I’ll continue adding more topics and diagrams as time unfolds.

Some of the dates (M/Y format) you see inside the individual markdown files may look older than the creation date of this public repository.
Here’s why:
- These notes were originally created and worked on in a private repository over the past 2–3 months.
- When I decided to make this section public, I copied the existing content into this new repository.
- The dates in the files reflect when each note was first written, not when this public repo was created.
✅ The content itself is accurate, complete, and represents my learning journey.
This note is here to clarify that older dates don’t mean outdated or irrelevant content — they just preserve the original creation history.
- Learners looking for a curated reference of networking concepts and diagrams
- Anyone exploring networking from basics to intermediate topics
- Those who appreciate organized, real-world explanations and examples
This repository isn’t about impressing anyone or presenting a “perfect” resource.
It’s a curated collection of networking concepts, diagrams, and explanations — built from multiple sources, organized for clarity, and refined through practice.
Each diagram, each markdown file, each explanation represents a small step in understanding networking more deeply.
The goal is to document, explore, and make learning tangible — one concept at a time.
This is not the “final word” on networking.
It’s a living resource — I’ll keep updating it with more concepts, notes, and diagrams as I learn further.
If you’re browsing through, welcome — this is how networking can be approached, understood, and referenced in a practical, structured way.
