IT k Funde・14 minutes read
The video explains the OSI model's seven layers and their role in network communication using real-life examples and analogies. It emphasizes understanding how each layer interacts and compares the OSI model to the TCP/IP model for clarity and encourages viewer engagement for a better grasp of the concept.
Insights
- The OSI model, comprising seven layers, facilitates the flow of information in network communication, with data moving from top to bottom during transmission and bottom to top during reception.
- By likening each layer to distinct army officers' responsibilities in a headquarters, the video underscores the necessity of comprehending how the OSI model's layers interact harmoniously, emphasizing practical examples and analogies for enhanced clarity.
