Networking Foundations
Complete beginners who want to understand how computer networks work.
Build a practical mental model for how modern networks move data.
Routing Protocols
Learners who already understand basic networking and want a rigorous, protocol-by-protocol understanding of dynamic routing.
Go deep on how routers actually choose paths: routing-table fundamentals, then RFC-grounded, packet-by-packet internals of RIP, OSPF, EIGRP, and BGP.
Security Protocols
Learners who already understand basic networking and want a rigorous, protocol-by-protocol understanding of how confidentiality, integrity, and authentication are achieved on the wire.
Go deep on how network security protocols actually protect data in transit: cryptographic fundamentals, then RFC-grounded, packet-by-packet internals of TLS, IPsec, SSH, and PKI.
Wireless Networking
Learners who already understand basic wired networking and want to understand how Wi-Fi's shared radio medium changes the rules for addressing, media access, and troubleshooting.
How Wi-Fi actually works over the air: radio frequency bands and channels, access point roles, and the media-access rules that let many devices share one invisible, half-duplex medium.
