A website, also written as web site,or simply site,is a set of related web pages typically served from a single web domain. A website is hosted on at least one web server, accessible via a network such as the Internet or a private local area network through an Internet address known as a uniform resource locator (URL). All publicly accessible websites collectively constitute the World Wide Web.
Web pages, which are the building blocks of websites, are documents, typically written in plain text interspersed with formatting instructions of Hypertext Markup Language (HTML, XHTML). They may incorporate elements from other websites with suitable markup anchors. Web-pages are accessed and transported with the Hypertext Transfer Protocol (HTTP), which may optionally employ encryption (HTTP Secure, HTTPS) to provide security and privacy for the user of the web-page content. The user’s application, often a web browser, renders the page content according to its HTML markup instructions onto a display terminal.
The pages of a website can usually be accessed from a simple Uniform Resource Locater (URL) called the web address. The URLs of the pages organize them into a hierarchy, although hyper linking between them conveys the reader’s perceived site structure and guides the reader’s navigation of the site which generally includes a home page with most of the links to the site’s web content, and a supplementary about, contact and link page.
