## The Internet and the web are different things The **Internet** is the global network of networks: millions of computers, phones, servers and routers joined by cables, fibre, satellites and radio links, all agreeing to exchange data using a common set of rules called protocols. The Internet carries many services, including email, file transfer, video calls and online games. The **World Wide Web** (WWW, or the web) is one of those services. It is a collection of linked documents and other resources, such as pages, images and videos, that can be reached over the Internet using a web browser. Tim Berners-Lee proposed it at CERN in 1989 and built the first working version in the early 1990s. The network already existed by then, which is why the two words are not interchangeable: sending an email does not use the web, but opening a page in a browser does. The web rests on three ideas: every resource has an address (a URL), the resources are requested and delivered using a protocol (HTTP or HTTPS), and the pages are written in a markup language (HTML) that lets one page link to another. ## Web servers and web clients A **web server** is a computer, together with the software running on it, that stores web content and sends it out when asked. It listens for requests, finds the file or builds the page that was asked for, and sends back a response. If it cannot find what was asked for, it sends back an error message instead.
