   The instructor begins by explaining Usenet, showing text that details how newsgroups contain conversations on specific topics. She then introduces E-commerce, underlining key terms like 'internet' and 'Example: Amazon, Flipkart'. As she speaks, she draws a diagram to illustrate network connectivity. This diagram features a stick figure representing a user connected to a computer server. She labels the connection line with 'PING' and 'ICMP' (Internet Control Message Protocol), indicating a check for reachability, which she writes as 'Reachable' next to the server. Finally, she writes 'Shopping' and 'Selling' on the left side of the screen to reinforce the core activities of e-commerce.

The lesson effectively bridges technical networking concepts with practical business applications. By defining Usenet and E-commerce, the instructor establishes a foundation for understanding how information and goods are exchanged over the internet. The diagram serves as a visual aid to explain how connectivity is verified using ICMP and PING, which is fundamental for the online transactions described in the e-commerce section. The handwritten notes emphasize the dual nature of e-commerce: buying (shopping) and selling.
