This course introduces the architecture, structure, functions, components, and models of the Internet and other computer networks. It uses the OSI and TCP layered models to examine the nature and roles of protocols and services at the application, network, data link, and physical layers. The principles and structure of IP addressing and the fundamentals of Ethernet concepts, media, and operations are introduced to provide a foundation for the curriculum.

As the first CCNA module, a mixture of equipment-based labs and simulations are used to allow participants to analyse real data without affecting production networks. Participants analyse protocol and network operation and build small networks in a simulated environment.

At the end of the course, participants build simple LAN topologies by applying basic principles of cabling; performing basic configurations of network devices, including routers and switches; and implementing IP addressing schemes.
