This course launches with the foundational networking concepts and physical layer technologies that underpin all network communications. Covering approximately 4 hours of expert instruction across networking fundamentals, the OSI and TCP/IP models, cabling standards, Ethernet, and structured cabling, learners build the conceptual and physical foundation for all subsequent networking studies. Learners benefit by understanding how data flows through networks, how physical media and connectors are selected and installed, and how to troubleshoot cabling problems. online labs reinforce physical installation and cable identification tasks. By the end of this course, learners will be able to describe network models, identify and install network media, and apply structured cabling standards to real-world installations.

Syllabus

Network Models & the OSI Framework

This chapter is a clear overview of core networking models and data flow, introducing frames, MAC addressing, ports, and essential TCP/IP protocols to build a strong foundation for understanding how networks communicate.

Cabling & Network Topology

This chapter is an introduction to essential network layouts and cabling, covering topologies, coax, twisted pair standards, fiber types, and cable fire ratings to build a solid understanding of modern network infrastructure.

Ethernet Basics

This chapter is a practical look at core Ethernet technologies, frames, cabling, topologies, and switch behavior, showing how networks are built, connected, and expanded in real-world environments.

Ethernet Standards

This chapter is a conscice look at Ethernet standards, transceivers, and common cabling or switch issues, building the skills needed to understand speeds, media options, and real‑world troubleshooting.

Installing a Physical Network

This chapter is a hands on guide to structured cabling, exploring its components, tools, testing methods, and troubleshooting techniques to ensure reliable, well‑built network installations.
