Computer Network Connecting Devices and Fundamentals

Building a solid understanding of computer networks starts with knowing how devices communicate and connect. This text-based course guides you through the foundational hardware that powers local and wide area networks, preparing you to confidently identify and configure key networking components. You will transition from learning basic terminology to understanding how data packets route across complex systems. What you will learn: Understand the roles of hubs, switches, routers, bridges, and gateways across different OSI layers; Analyze how data flows through physical and logical network pathways; Practice identifying proper device placement for secure and efficient network topologies; Explore modern network fundamentals including basic virtual local area networks (VLANs) and modern zero-trust security concepts; Evaluate your knowledge with targeted practice questions designed to reinforce core networking theories. This course begins with essential definitions and foundational models before diving into specific hardware functions and real-world scenarios. It is designed specifically for beginners with no prior networking experience who want a clear, structured path to mastering network infrastructure.
