Packet Tracer will help you better understand networking concepts as you simulate networks.

Cisco Packet Tracer is a powerful network simulation program that allows students to experiment with network behavior and ask “what if” questions. As an integral part of the Networking Academy comprehensive learning experience, Packet Tracer provides simulation, visualization, authoring, assessment, and collaboration capabilities and facilitates the teaching and learning of complex technology concepts.

Packet Tracer supplements physical equipment in the classroom by allowing students to create a network with an almost unlimited number of devices, encouraging practice, discovery, and troubleshooting. The simulation-based learning environment helps students develop 21st century skills such as decision making, creative and critical thinking, and problem solving.

Packet Tracer 5.3 installer is available for free download in this blog entry. Tutorials about Packet Tracer might be available some time soon.

Taking up CCNA 2 (Cisco Certified Network Associate – Routing Protocols and Concepts) ? These Powerpoint slides might help you in your study. They are not actually the course materials that you will be able to view as a student. They are the materials being used by instructors. I prefer reviewing using these because they are simpler. And no, no. This ain’t cheatsco. lol.
