    The session begins with the instructor writing Internet - global and facilities on a blank slide titled Role of Internet and Web services. As the slide content loads, text explains that the Internet allows users to upload or download files like software, videos, and audio. The instructor underlines the phrase source of knowledge and communication to stress its importance. She then focuses on data exchange services, specifically listing FTP, Telnet, and VoIP. Handwritten notes appear, clarifying that FTP relates to File transfer and Telnet allows for Remotely connecting, while she also adds email and chat msg as examples of communication services. The visual progression moves from general definitions to specific technical protocols used for data exchange, illustrating the breadth of internet utility.

This segment establishes the foundational utility of the Internet beyond just connectivity. By categorizing services into file transfer (FTP), remote access (Telnet), and voice (VoIP), the lecture provides a structured view of how data moves across networks. The handwritten annotations serve to simplify technical acronyms, linking FTP directly to file management and Telnet to remote operations, ensuring students grasp the practical application of these protocols in a global context. The emphasis on exchange data highlights the functional purpose of these services in maintaining networked communication.
