Internet Encyclopedia Entry 1782643351

** This encyclopedia entry is about the **World Wide Web**, a system of interlinked hypertext documents that can be accessed via the **Internet**. **CONTENT** ### Overview The **World Wide Web** (WWW) is a system of interlinked hypertext documents that can be accessed via the **Internet**. It was invented by **Tim Berners-Lee** in 1989 while working at **CERN**, the European Organization for Nuclear Research. The web was initially designed to facilitate the sharing of information among physicists, but it quickly grew to become a global network of interconnected documents, images, videos, and other multimedia content. The web is built on top of the **Internet Protocol (IP)** and uses **HTTP (Hypertext Transfer Protocol)** to transfer data between servers and clients. The web is often confused with the **Internet**, but they are not the same thing. The **Internet** is a global network of interconnected computers and servers that communicate using **IP addresses**, while the **World Wide Web** is a system of interlinked documents that can be accessed via the **Internet**. Think of the **Internet** as the underlying infrastructure and the **World Wide Web** as the user-friendly interface on top of it. The web has revolutionized the way we access and share information, and it has had a profound impact on modern society. It has enabled global communication, e-commerce, online education, and many other applications that have transformed the way we live and work. ### History/Background The history of the **World Wide Web** dates back to 1980, when **Tim Berners-Lee** began working at **CERN** as a software engineer. At the time, CERN was facing a problem of how to share information among physicists working on different projects. Berners-Lee proposed the idea of a system of interlinked documents that could be accessed via the **Internet**. He wrote a proposal for the **World Wide Web** in March 1989, and he began working on the project in May 1989. Berners-Lee's initial proposal was rejected by his colleagues, but he continued working on the project in his spare time. He developed the first web browser, called **WorldWideWeb**, and the first web server, called **httpd**. He also developed the **HTTP (Hypertext Transfer Protocol)**, which is still used today to transfer data between servers and clients. The **World Wide Web** was first made available to the public in August 1991, and it quickly gained popularity. In 1993, the first graphical web browser, called **Mosaic**, was released, and it made it easy for non-technical people to access and navigate the web. ### Key Information * **Key dates:** + 1980: **Tim Berners-Lee** begins working at **CERN**. + 1989: Berners-Lee proposes the idea of the **World Wide Web**. + 1991: The **World Wide Web** is first made available to the public. + 1993: The first graphical web browser, **Mosaic**, is released. * **Key technologies:** + **HTTP (Hypertext Transfer Protocol)**: a protocol for transferring data between servers and clients. + **HTML (Hypertext Markup Language)**: a markup language for creating web pages. + **URL (Uniform Resource Locator)**: a standard for addressing web pages. * **Key achievements:** + The **World Wide Web** has enabled global communication, e-commerce, online education, and many other applications. + The web has revolutionized the way we access and share information. ### Significance The **World Wide Web** has had a profound impact on modern society. It has enabled global communication, e-commerce, online education, and many other applications that have transformed the way we live and work. The web has also enabled the creation of new industries, such as e-commerce and online advertising, and has created new opportunities for entrepreneurs and small businesses. The web has also had a significant impact on the way we access and share information. It has enabled the creation of online communities, social networks, and online forums, which have transformed the way we communicate and interact with each other.
