The OSI model - 7 layers explained in under 5 minutes
Welcome to a lightning-fast journey through the OSI model! In this 5-minute video, we'll explain the 7 layers that form the foundation for network communication in an easy-to-understand way.
🔍 What can you expect?
Physical Layer: Here we start with the basics of zeros and ones, the physical signal that carries our data.
Data Link Layer: Learn how errors are detected and corrected at the bit level and why MAC addresses play a key role.
Network Layer: Dive into the world of internet packet transmission and discover how different networks communicate with each other.
Transport Layer: This is where data streams are segmented and reassembled using the well-known TCP protocol.
Session Layer: Discover how sessions are established, managed, and terminated between different devices to ensure seamless communication.
Presentation Layer: Learn how data is prepared for the higher application layer and why data compression is important.
Application layer: The interface between the software application and the lower layers. Functions are provided here to enable communication. A look at the HTTP protocol completes the explanation.
