Become Confident With Networks — and Pass Network+
Every connected device, website, and app rides on a network. This track teaches you how those networks actually work, one clear step at a time, and prepares you for the industry-standard CompTIA Network+ (N10-009) exam. No prior experience is assumed — you start with what a network even is and build all the way to subnetting, routing, wireless security, and structured troubleshooting that real technicians use every day.
What You Will Learn
You will master the OSI and TCP/IP models and how data is wrapped and sent as packets, then work through cabling and devices, IPv4 and IPv6 addressing, and subnetting made approachable. You will learn the ports and protocols that power the internet, how DNS and DHCP work, switching with VLANs, routing fundamentals, and wireless networking and its security. Advanced courses cover NAT and network services, cloud and virtual networking, security foundations, common attacks and defenses, VPNs, monitoring with SNMP and syslog, and a complete troubleshooting methodology with the command-line tools every tech relies on.
The Learning Path
Thirty courses progress from A1 to B2. You begin with What a Network Really Is, The OSI Model Made Simple, and The TCP/IP Model in Practice, build the core with IPv4 Addressing Essentials, Subnetting Without Fear, Ports and Common Protocols, and DNS: How Names Become Addresses, then advance through Switching: VLANs and Loop Prevention, Routing Fundamentals, Securing Wireless Networks, and Network Security Foundations, finishing with Troubleshooting Methodology, Command-Line Diagnostic Tools, and Performance and High Availability.
How It Works
Each course is broken into short, focused lessons with clear explanations, real command examples, and a quick quiz to lock in exam-relevant facts. Acronyms are defined the first time they appear, and an AI tutor is on hand whenever a concept needs a second pass — so you build genuine understanding, not just memorized answers.
