Nexus was a browser-editor, allowing users to also create pages, not only browse them. It was called The WorldWideWeb, but was renamed Nexus to avoid any confusions. The first browser appeared in 1990, created by W3C Director Tim Berners-Lee. Browsers can also display other more advanced material like interactivity and animations made with JavaScript with internal JavaScript interpreters. The browser then communicates with the network to ask for all the documents that make up the page. After that, it sends a Hypertext Transfer Protocol (HTTP) request to the web server, which sends a response with HTML, CSS, and other content files to the browser. This basically means that every URL has an equivalent set of numbers – the IP address – and the DNS translates it into language so we can type “” instead of “74.125.134.102”. It does this by first performing a Domain Name System (DNS) look to find the correct IP address. When you search something on Google and click on a link or enter a URL in the address bar, the webserver locates and sends the information you just requested to the web browser. The browser acts as a client to contact the web server and request information.
