Step 1: Provide a literature-based description of the Web and distinction of the terms. The World Wide Web (WWW or Web) is a system of interlinked hypertext documents, resources, and multimedia content stored on servers around the world and accessed over the Internet using web browsers. According to Tim Berners-Lee (1989, CERN proposal), the Web was invented to create a global hypertext project enabling information sharing without centralized control: "I have seen a possible next step... making an analysis and description of available and future hypertext facilities so that they can choose and integrate them into a single system." Distinction of terms: Internet: Global network of interconnected computer networks using TCP/IP protocols for data transmission. World Wide Web: Application/service running on the Internet, using HTTP/HTTPS protocols, HTML for structure, URLs for addressing, and hyperlinks for navigation. The Web is part of the Internet, but not all Internet services (e.g., email via SMTP) are part of the Web. Step 1.2: Summarize the key components of the World Wide Web. The WWW consists of four main components: 1. Client-side (Web Browser): Software (e.g., Google Chrome, Mozilla Firefox) that requests and displays web content. 2. Server-side (Web Server): Software (e.g., Apache, Nginx) that stores and delivers web pages/resources. 3. Protocols: HTTP/HTTPS for communication between client and server; TCP/IP underlying transport. 4. Content Languages/Formats: HTML for structure, CSS for styling, JavaScript for interactivity; URLs for resource identification. Step 1.3: Identify three examples of communication technologies. Three examples of communication technologies (in context of data sharing/transfer via ICT): 1. Email: Asynchronous text/multimedia messaging (e.g., Gmail using SMTP/IMAP protocols). 2. Instant Messaging: Real-time text/voice chat (e.g., WhatsApp using XMPP/WebSocket). 3. Video Conferencing: Synchronous audio-video calls (e.g., Zoom using RTP/RTCP over UDP). Final answers: 1. Web: Interlinked hypertext system on Internet (Berners-Lee 1989). Distinction: Internet = network; Web = service. 1.2 Components: Browser, Server, HTTP, HTML/URLs. 1.3 Examples: Email, Instant Messaging, Video Conferencing.
