World of Computer Networking Your CCNA start - Encapsulation and Decapsulation

The video tutorial explains the OSI and TCP/IP models, focusing on the processes of data encapsulation and decapsulation. Encapsulation involves adding headers at each layer, while decapsulation involves removing them on the recipient side. The tutorial highlights the independence of each layer and the flexibility of using different protocols. It concludes with a summary and a transition to discussing the data link layer and Ethernet protocol.

What is the significance of checksums in the data link layer?

How do different layers of the OSI model interact with each other during data transmission?

How does the application layer remain independent of the technologies used in lower layers?
