The World Wide Web, commonly known as the WWW or the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators (URLs), which may be interlinked by hypertext, and are accessible over the Internet. The resources of the Web are transferred via the Hypertext Transfer Protocol (HTTP) and may be accessed by users via a software application called a web browser.
History and Origin of the World Wide Web
The concept of the World Wide Web was pioneered by British scientist Tim Berners-Lee in 1989 while working at CERN. The first website, created by Berners-Lee, went live on August 6, 1991. It was dedicated to information on the World Wide Web project and was made available to the public from the CERN web server.
Key Features of the World Wide Web

Proxy Servers and the World Wide Web
Proxy servers play a crucial role in the context of the World Wide Web. They act as intermediaries between end-users and web servers, offering various benefits:
- Privacy and Anonymity: Hiding the user’s real IP address.
- Security: Filtering malicious content and preventing direct attacks.
- Access Control: Restricting or enabling access to certain websites.
- Caching: Speeding up web browsing by storing frequently accessed resources.
- Geographical Spoofing: Accessing geo-restricted content by masking the user’s location.
