Build the foundational networking skills and physical layer knowledge that underpin all network communications. Through the industry-proven lens of the CompTIA Network+ (N10-009) exam, this course builds the vocabulary every network professional needs: the OSI and TCP/IP models, frames and MAC addresses, topologies, cabling standards, Ethernet, and structured cabling. You'll learn how data flows through networks, how physical media and connectors are selected and installed, and how to track down cabling problems. Online labs reinforce physical installation and cable identification.

Not planning to take the exam? The skills still apply on the job. Whether you support a small office network or simply want to understand how networks really work, this course gives you a practical foundation you can use right away. Clear, expert instruction makes each concept approachable, and the first module is designed as an accessible entry point, so you can start with confidence even if networking is new to you.
