The majority of websites have a home page with underlying content pages, although some websites contain only a single page.
The uniform resource locator (URL) of a home page is most often of the form http://domain.tld/index.htm or http://domain.tld/default.htm, where "tld" refers to the top-level domain used by the website. However, if the /index.htm or /default.htm is omitted, the server will still serve the page.
For example, http://www.example.com and http://www.example.com/index.html both refer to the example.com homepage. The index.htm file is kept in the highest level of the directory the server is configured to serve.
If an index.htm home page has not been created for a web site, many web servers will default to display a list of files located in the site's directory, if the security settings of the directory permit. This list will include hyperlinks to the files, allowing for simple file sharing without maintaining a separate index file.
A home page can also refer to the first page that appears upon opening a web browser, sometimes called the start page, although the home page of a website can be used as a start page. This start page can be a website, or it can be a page with various browser functions such as the display of thumbnails of frequently visited websites. Multiple websites can be set as a start page, to open in different tabs. Some websites are intended to be used as start pages, such as iGoogle (now defunct), My Yahoo!, and MSN.com, and provide links to commonly used services such as webmail and online weather forecasts.
A home page can also be used outside the context of web browsers, such as to refer to the principal screen of a user interface, frequently referred to as a home screen on mobile devices such as mobile phones.
