World of Computer Networking Your CCNA start - Mapping Captured Data Packets to Transmission Control Protocol/Internet P

The video tutorial provides an overview of the TCP/IP model layers and demonstrates how to use Wireshark to capture and analyze network packets. It explains the alignment of different protocols to the TCP/IP layers, focusing on TCP, UDP, and DNS protocols. The tutorial also introduces the OSI model, highlighting its seven layers compared to the four layers of the TCP/IP model. Practical examples using Wireshark are provided to illustrate the concepts, including capturing packets from Google Chrome and analyzing their protocol layers.

Describe the function of the network access layer as outlined in the text.

How does the OSI model differ from the TCP/IP model according to the text?
