What is Web ?

The World Wide Web, or simply the web, is an extensive network of interconnected resources and documents accessible through the internet. Its inventor, Sir Tim Berners-Lee, created it in 1989 to facilitate information sharing among CERN researchers. Today, it is an integral part of modern life, enabling global communication, collaboration, and access to vast amounts of information.

The web's foundation is a set of standards and protocols that define how information is organized and transmitted over the internet. Among the most significant of these is the Hypertext Transfer Protocol (HTTP), which facilitates requesting and transmitting web pages and other resources. Other crucial web technologies include Hypertext Markup Language (HTML), which structures web pages, and Cascading Style Sheets (CSS), which governs their presentation and layout.

Web content comprises web pages, which are commonly created with HTML and other web technologies and can include text, images, audio, video, and other forms of content. They can also link to other web pages or resources using hyperlinks. Web pages are usually hosted on web servers, which are computers connected to the internet and configured to respond to HTTP requests.

To access the web, users typically use web browsers, which are software applications that allow them to view and interact with web pages. Popular web browsers include Google Chrome, Mozilla Firefox, Microsoft Edge, and Apple Safari. When a user enters a web address (URL) into their browser, the browser sends an HTTP request to the web server hosting the requested resource, and the server responds with the requested content.

The web has revolutionized communication, commerce, education, and entertainment, providing people with the ability to access information and resources from anywhere in the world, opening new possibilities for collaboration and innovation. However, it also presents various challenges, such as the spread of false information, cybercrime, and privacy concerns. As the web continues to grow and develop, it will be necessary to tackle these challenges and ensure that the web remains an accessible, open, and safe platform for all.
