Free CCNA 200-301 Course: Network Fundamentals

A Free Primer on Core Networking Devices

This free course covers the Network Fundamentals portion of the CCNA 200-301 exam blueprint — material that also overlaps directly with the CompTIA Network+ exam. Rather than trying to cover the entire certification, it focuses squarely on the building blocks every networking student needs first: what the core devices actually do and how they fit together.

Devices Covered

• Repeaters and hubs
• Bridges and switches
• Routers
• Clients and servers

Alongside the devices, the course also introduces port numbers and other fundamentals that show up repeatedly on the CCNA exam.

Who It's For

Beginners starting a CCNA or Network+ study plan who want a clear, no-cost introduction to the fundamentals before tackling routing, switching, and more advanced topics. A solid grasp of these basics is the foundation the rest of networking study builds on.
