This course introduces the core networking concepts every IT technician must understand, from physical media and network topologies to the TCP/IP protocol suite. Covering approximately 4 hours of expert instruction, learners develop a solid foundation in how networks are built, how data moves across them, and how IP addressing works in both IPv4 and IPv6 environments. Learners benefit by gaining the networking knowledge required to configure, support, and troubleshoot small and enterprise networks. Online labs reinforce network topology identification, cable termination, IP address configuration, and protocol analysis. By the end of this course, learners will be able to identify network media and topologies, explain the OSI and TCP/IP models, configure IP addressing, and understand the function of common network protocols and services.
