Computer Networks

The internet didn’t appear by magic – it’s built on the fascinating world of computer networks. This course takes you behind the scenes to understand how data travels across the globe, from your home Wi‑Fi to massive data centres. You’ll learn the fundamental concepts that keep our connected world running: IP addressing, routing, switching, network protocols (TCP/IP, HTTP, DNS), and how local area networks (LANs) connect to the wider internet. We’ll start with everyday analogies – like how sending a letter compares to sending a data packet – so even complex topics like subnetting and the OSI model become clear and memorable. You’ll gain hands‑on experience with tools like Wireshark and Cisco Packet Tracer, simulating real networks and troubleshooting common issues. Whether you’re aiming to become a network administrator, cybersecurity specialist, or cloud architect, or you simply want to know how your devices actually “talk” to each other, this course gives you the essential knowledge to work confidently with modern networks. Our expert instructors will guide you step‑by‑step, with plenty of practical exercises. No prior networking knowledge required – just basic computer skills and a curiosity about how the internet really works!
