A web site is a collection of web pages images, videos or other digital assets that is hosted on one or more web servers, usually accessible via the internet. Some websites require a subscription to access some or all of their content. Examples of subscription sites include many business sites, parts of many news sites, academic journals sites, gaming sites, message boards, Web-based E-mail, and social networking websites. The pages of a website can usually be accessed from a common root URL called the homepage.
