Learnet: Networking Basics

Learnet is a learning app that makes networking fundamentals stick by "read first, then solve." Every topic follows the same flow: a short illustrated lesson first, then a quick quiz to check your understanding. The lessons lean on hand-built diagrams and animations — packets traveling through a router, an L2 switch learning MAC addresses, the bits of a subnet mask — so the ideas click instead of having to be memorized.
