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.
