A A  WHAT IS WEB? The term "web" typically refers to the World Wide Web, often abbreviated as the "web." The World Wide Web is a system of interlinked hypertext documents accessed via the Internet. These pages and documents are interconnected by means of hyperlinks that users click on for information. This information can be in different formats, including text, images, audio and video. HOW DOES WORLD WIDE WEB WORK? The World Wide Web (WWW) can be likened to a vast electronic book comprised of pages stored on servers globally. These pages are interconnected through hyperlinks, enabling navigation between different documents. Hyperlinks are integral to the WWW, facilitating access from one part of a document to another or to entirely different documents, defining its interconnected nature. KEY TECHNOLOGIES UNDERPIN THE FUNCTIONING OF THE WEB: 1. HTTP 2. HTML 2. URL (Uniform (Hypertext Transfer (Hypertext Markup Resource Locators) Protocol) Language) This is the protocol HTML is the URLs are addresses used for transmitting data standard markup language used to identify resources on between web servers and used for creating and the web. They specify the web browsers. It defines structuring web pages. It location of web pages, files, how messages are provides a set of tags or or other resources, allowing formatted and transmitted, elements that define the users to access them using allowing for the retrieval structure and content of a web browsers. A typical URL and display of web webpage, including consists of several content. headings, paragraphs, components, including the images, links, and more. protocol (e.g., "http://" or "https://"), the domain name (e.g., "example.com"), and the path to the specific resource.  HISTORY OF WORLD WIDE WEB ❖ Tim Berners-Lee, a British physicist, invented the World Wide Web (WWW) while working at CERN since 1989. Berners-Lee aimed to create a user-friendly system for global communication and information sharing by combining existing technologies and data networks. The first WWW server, named httpd, and client were developed by Berners-Lee and his colleagues at CERN. Originally, the WWW was a WYSIWYG hypertext browser/editor running in the NextStep environment.  HISTORY OF WORLD WIDE WEB In 1990, Berners-Lee demonstrated the first web server and browser at CERN, outlining his vision for the WWW. The public became aware of the WWW in 1991 when Berners-Lee announced it on the alt.hypertext newsgroup and created the first web page at http://info.cern.ch/hypertext/WWW/TheProject.html. This page, operational as of 2022, provides information and links about the WWW project and web servers. In 1993, CERN made the WWW technology publicly available on a royalty-free basis.  What will Web 3.0 look like compared to Web 1.0 and 2.0? Web 1.0, originating from Tim Berners-Lee's vision in 1989, was static and focused on providing information. It lacked video content and resembled printed pages, primarily serving as a repository of static data. Web 2.0 emerged around the turn of the 21st century, introducing a more interactive and dynamic web experience. This era emphasized user collaboration, universal network connectivity, and communication channels. Applications like Airbnb, TikTok, Twitter, and Uber thrived, increasing online interactivity and utility, fueled by the proliferation of smartphones, mobile internet access, and social networks.  What will Web 3.0 look like compared to Web 1.0 and 2.0? Web 3.0, still in its nascent stages, aims to create more intelligent, connected, and open websites. It's envisioned as a fully decentralized web, unlike Web 2.0, where content creation shifts from platform owners to content creators. While the concept of Web 3.0 remains under development, its potential promises a paradigm shift towards a more democratized and user-controlled internet landscape.  IMPORTANCE OF WEB IN TODAY’S WORLD The World Wide Web plays a crucial role in today's world across various sectors, influencing how we communicate, work, learn, and conduct business. COMMUNICATION EDUCATION The World Wide Web serves as a foundational tool and platform for innovation, collaboration, and connectivity across diverse sectors, driving societal advancement and digital GOVERNMENT COMMERCE transformation in today's interconnected world. Key d i f f e r e n c e between w e b s i t e a n d webpage A webpage is a smaller part of any website having content and links to other webpages. On the contrary, a website is a platform that contains various webpages addressed to certain URLs (Uniform Resource Locators). A website is simply a place that allows developers to display the contents and attach hyperlinks. On the other hand, a web page is a content or a document itself that is to be displayed on the website. Typically, a webpage contains content about a solitary entity or a topic, whereas the website is a place that contains content from different entities or topics linking certain hyperlinks. A THE INTERNET The Internet is like a big virtual highway that connects computers all around the world. It lets people send messages, share pictures, and find information. ORIGIN OF THE INTERNET In the 1960s, the U.S. government created something called ARPANET, a kind of early Internet, to help computers share information. Web VS Internet While internet is a big network that connects computers globally, web is a SYSTEM on the internet for viewing and sharing web pages. (ex: abs-cbn news, e commerce website such as: Lazada, Shopee, banking website like BDO online banking)  COMPARISON 1. Basic Structure -internet: Physical stuff (like cables) and rules (protocols) for sending data globally. - web: Uses the internet but adds specific rules for viewing web pages. 2. Functions: -internet: use for emails, gaming, file sharing and more. -web: mainly used for viewing web pages. 3. Accessibility: - internet: foundation of online services - web: part of the internet used for viewing web pages. CONCLUSION The internet is like the big network connecting everything, while the Web is a part of it designed for used for searching web pages. Both work together to make the digital world we use every day.  NOTE: The term World Wide Web isn't synonymous with the internet. Rather, the World Wide Web is part of the internet.  REFERENCES: https://www.techtarget.com/whatis/definition/World-Wide-Web https://www.usg.edu/galileo/skills/unit07/internet07_02.phtml https://www.simplilearn.com/what-is-web-1-0-web-2-0-and- web-3-0-with-their-difference-article Thank You:
