Explore open-source projects and educational resources that explain core internet protocols and network architecture concepts.
This project consists of technical instructional guides and a structured computer science curriculum designed to teach the construction of a full computing stack from transistors up to a web browser. It provides a 12-week educational course that covers the fundamental domains of computer architecture and digital logic design. The curriculum is distinguished by its first-principles approach, guiding the learner through the engineering of CPUs, FPGAs, and PCBs using digital logic and hardware description languages. It includes specific syllabi for building a hardware design, a TCP/IP network st
This open-source curriculum guides you through building a TCP/IP network stack from scratch as part of a full computing stack, making it a practical, hands-on resource for understanding how the internet works, though it covers the broader computer architecture rather than focusing solely on interactive networking simulations or visual protocol diagrams.
GNS3 Graphical Network Simulator
GNS3 is an interactive network simulator that lets you build and inspect complex network topologies, run real devices, and capture live packets, making it a practical hands-on tool for learning TCP/IP and internet workings through labs and visual topology diagrams.
