Network Fundamentals
Test Preparation
Course Introduction
Network Fundamentals introduces students to the foundational concepts of computer networking, including the structure, function, and design of networked systems. The course covers key topics such as networking models (OSI and TCP/IP), media types, protocols, addressing, and network hardware components. Students learn about local area networks (LANs), wide area networks (WANs), and basic network security measures. Emphasis is placed on understanding how data is transmitted across networks, troubleshooting common network issues, and the role of various devices like routers, switches, and hubs. This course provides essential knowledge for advancing to more specialized networking topics and certifications.
