Networks and Communication

Ever wondered how you can share photos in an instant, collaborate in real-time with colleagues continents away, or stream your favorite concert live from across the globe? It all comes down to networks—the hidden framework that seamlessly connects people, devices, and data around the world.

In the Networks and Communication course, instructor Alan guides you through the powerful, invisible systems that make modern connectivity possible. Whether you’re an aspiring IT pro, a tech enthusiast, or simply curious about what happens behind the scenes, this course will demystify the fascinating world of networks.

What You’ll Learn:

Network Fundamentals:

Discover what a network really is, how it enables devices to share information, and the differences between small home networks, huge corporate infrastructures, and global systems. Compare peer-to-peer and client-server models to see how devices connect and interact.

Inside the Internet:

Explore the Internet as the ultimate network of networks. Learn how your data—whether an Instagram post or a video call—travels the world in packets, navigating different routes to reach the right destination as quickly and reliably as possible.

Essential Hardware:

Get hands-on with the hardware that powers networks, including routers, switches, and modems. Understand how the physical design (topology) of a network affects its performance, and weigh the benefits of wired versus wireless connections.

Communication Protocols:

Unpack the rules that organize digital conversations. Dive into protocols like TCP, IP, and HTTP, and learn how addressing systems like IP and MAC guide data to the right device. See how public and private IPs serve different networking needs.

Troubleshooting Skills:

Equip yourself with essential troubleshooting tools—such as ping, ipconfig/ifconfig, and traceroute—to diagnose and fix common connection issues, whether they arise on wired or wireless networks.

Throughout the course, you’ll connect complex concepts to everyday experiences—making sense of the technology that keeps our world connected. As part of the KodeKloud community, you’ll engage with other learners, share your discoveries, and get support every step of the way.
