Packet Tracer Labs: Connectivity Tests (PCs, Switches, Ping & ARP)
In this first Packet Tracer course video, we start from scratch: downloading Packet Tracer from NetAcad, installing it on Ubuntu, fixing common launch issues, and configuring the environment correctly. Then we jump straight into hands-on labs to understand how basic network connectivity really works. 💻🌐
You’ll learn PC-to-PC connections, switch-based networks, IP addressing, subnet masks, ping testing, and how ARP tables are populated step by step. This video is perfect for beginners, IT students, and anyone preparing for networking fundamentals or CCNA concepts. 🚀📡
