World Wide Web (WWW)

Overview

What is the World Wide Web (WWW)?

The World Wide Web (WWW), commonly known as the Web, is a system of interlinked hypertext documents and resources that are accessed via the Internet. It allows users to view webpages that may contain text, images, videos, and other multimedia, and to navigate between them via hyperlinks. The WWW was invented by Tim Berners-Lee in 1989 while he was at CERN (the European Organization for Nuclear Research).

Key Features

Hypertext - This is text displayed on a computer display or other electronic devices with references (hyperlinks) to other text that the reader can immediately access.
URLs (Uniform Resource Locators) - Addresses used to locate content on the Web.
HTML (Hypertext Markup Language) - The standard markup language for documents designed to be displayed in a web browser.
HTTP (Hypertext Transfer Protocol) - The protocol used to transmit hypertext over the Internet.
Web Browsers - Software applications such as Google Chrome, Mozilla Firefox, and Microsoft Edge that are used to access and navigate the WWW.

Example

Google - A widely used search engine and suite of tools available via the Web.
Wikipedia - An online encyclopedia that is a vast source of hypertext documents maintained collaboratively by its users.
Amazon - An online shopping website showcasing hypertext-based product catalogs linked to individual product details.

Frequently Asked Questions (FAQs)

What was the first-ever website?

The first-ever website was created by Tim Berners-Lee and was hosted on his NeXT computer at CERN. It primarily provided information on the World Wide Web project itself.

How does the WWW differ from the Internet?

The Internet is a global network of interconnected computers, whereas the WWW is a collection of information accessible via the Internet. The Web uses the Internet to transmit data between client browsers and web servers.

How do hyperlinks work?

Hyperlinks are pieces of text or images on a webpage that, when clicked, direct the browser to a new webpage or resource. They are usually implemented using the <a> tag in HTML.

What are some security considerations when using the Web?

Users should be aware of threats such as phishing, malware, and data breaches. Using secure connections (HTTPS), employing strong passwords, and being vigilant about the authenticity of websites can reduce these risks.

What advancements are being made with the WWW?

Technological advancements like the Semantic Web, web machine learning, and artificial intelligence integration are the latest trends pushing the boundaries of how the Web can be used.

Internet: A global network connecting millions of private, public, academic, business, and government networks.

HTML (Hypertext Markup Language): The standard markup language used to create and design webpage content on the WWW.

HTTP (Hypertext Transfer Protocol): The foundation protocol used for transmitting hypertext on the Web.

Web Browser: A software application for retrieving, presenting, and traversing information resources on the WWW.

URL (Uniform Resource Locator): The address used to access resources on the World Wide Web.
