OSI Model Explained for Beginners | 7 Layers & How Data Travels | Data Center Series Ep. 4.1

"Episode 4.2 coming soon" Welcome to Episode 4 of our Data Center and Networking series! In this video, we explore what happens when PC1 communicates with PC2 across a network. We begin with the Ping command to check basic IP connectivity before transferring actual data. Using an employee-information Excel file as a practical example, we examine how data is prepared, divided, addressed, transmitted and finally reconstructed at the destination. You will learn: What the OSI model is Why networking uses seven layers Why the OSI model is not software, hardware or a configuration How Ping checks whether another device is reachable How data travels from PC1 to PC2 What happens at each of the seven OSI layers The meaning of data, segments, packets, frames and bits How protocols, addresses, headers and network devices participate in communication This beginner-friendly explanation uses practical examples and visual diagrams to make the OSI model easier to understand.
