This course provides a structured introduction to networking fundamentals, designed to help beginners understand how computers communicate over networks and the internet. It focuses on the core building blocks of modern networking systems and how data is transmitted between devices.

You will learn about essential network devices such as hosts, hubs, switches, bridges, and routers, and how each component plays a role in moving data efficiently across networks. The course also explains IP addressing and how devices are identified and connected within local and global networks.

A major focus is placed on the OSI model, which breaks down network communication into layers to simplify understanding of complex interactions. You will explore how data moves through each layer and how protocols ensure reliable communication.

The course also covers how hosts interact with the internet, including how packets are created, transmitted, and routed. It explains in detail how switches manage local network traffic and how routers direct data between different networks.

By the end of this course, learners will have a strong understanding of how networks operate at both a conceptual and practical level. It is ideal for beginners in IT, networking, cybersecurity, or anyone preparing for networking certifications.
