The World Wide Web (WWW), commonly referred to as the web, is a global system of interconnected documents and resources accessible via the Internet. It was developed in the late 20th century by British computer scientist Tim Berners-Lee and his team at CERN (European Organization for Nuclear Research) as a means of sharing and accessing information across different computer networks.
The World Wide Web comprises millions of web pages containing text, images, videos, hyperlinks, and other multimedia content, organized into websites hosted on web servers distributed worldwide. Users access web content using web browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, and Opera, which interpret and render web pages according to HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and other web technologies.
The key components of the World Wide Web include:
a. Web Servers: Web servers are computer systems that store and serve web content to users over the Internet. They host websites and web applications, responding to HTTP (Hypertext Transfer Protocol) requests from client devices and delivering web pages and resources in response.
b. Web Browsers: Web browsers are software applications that enable users to access and navigate the World Wide Web. They provide interfaces for viewing web pages, following hyperlinks, submitting forms, and interacting with web-based content and services.
c. Hyperlinks: Hyperlinks, or simply links, are clickable elements embedded in web pages that allow users to navigate between different web resources. They connect related content across the web, enabling seamless exploration and information retrieval.
d. Uniform Resource Locators (URLs): URLs are standardized addresses used to identify and locate resources on the World Wide Web. They specify the protocol (e.g., HTTP, HTTPS), domain name, and path to access web pages, files, or services.
e. Hypertext Markup Language (HTML): HTML is the standard markup language used to create and structure web documents. It defines the structure and layout of web pages, incorporating text, images, links, forms, and other elements to create interactive and visually appealing content.
f. Web Standards and Protocols: The World Wide Web operates based on a set of open standards and protocols, including HTTP, HTML, CSS, JavaScript, and others, established by international organizations such as the W3C (World Wide Web Consortium). These standards ensure interoperability, accessibility, and compatibility across different web platforms and devices.
The World Wide Web has become an indispensable tool for communication, collaboration, commerce, entertainment, education, and information dissemination, revolutionizing the way people access and interact with digital content on a global scale.
