This course provides an introduction to wired network infrastructures, topologies, technologies, and the protocols required for effective end-to-end communication. Basic security concepts for TCP/IP based technologies are introduced. Networking layers 1, 2, and 3 are examined in-depth using the International Standards Organization’s Open Systems Interconnection and TCP/IP models as reference. Course topics focus on the TCP/IP protocol suite, the Ethernet LAN protocol, switching technology, and routed and routing protocols common in TCP/IP networks. The lab assignments mirror the lecture content , providing an experiential learning component for each topic covered.
