The Web is based on a set of rules for exchanging text, images, sound, video, and other multimedia files, which is collectively known as HTTP, or hypertext transfer protocol. But everything would still be chaos if the Web didn't have an addressing scheme that every computer on the network understands. In addition, web servers also use an alias system that allows one or more non-numeric or symbolic addresses, when typed into a web browser, to connect to the webserver. Internet domain names are the next level of Internet addressing, just as the street name is followed by the city and state.
Domain names create a single identity for a series of computers used by a company or an institution.
The domain name identifies all the computers in a group. But if you want to get to a specific page stored on any of those computers, you'll need an even more precise address. High level domain names refer to the final suffix in the full domain name. A high level domain name identifies the type of site where the web server resides. The following are new domain names that has recently been approved.
