CIS 221 - Networking Fundamentals

3 Credits

This course introduces architecture, structure, functions, components and models of the Internet and other computer networks. The OSI and TCP layered models are used to examine the nature and roles of protocols and services at the application, network, data link, and physical layers. Principles and structures of IP addressing, and the fundamentals of Ethernet concepts, media and operations are introduced to provide a foundation for the curriculum. Labs use a virtual machine to allow students to analyze real data without affecting production networks. Packet Tracker activities help students analyze protocol and network operations and build small networks in a simulated environment. Students build simple LAN topologies by applying basic principles of cabling, performing basic configurations of network devices such as routers and switches and implementing IP addressing schemes.
Prerequisites: CIS 220.
