A website is a presence on the World Wide Web. As of 2021, there are more than one billion. To qualify as a bona fide site, it must be available over the Internet around the clock. Rendered with various spellings ("Web site," "web site" and "Website"), a website is a collection of Web pages (files) coded in HTML that are linked to each other and to pages on other sites. A website is run (hosted) on a Web server by the site's owner, a Web hosting provider or an Internet service provider (ISP). See
