A
website (also spelled Web site or web site)
is a collection of related web pages,
images, videos or other digital assets that
are addressed with a common domain name or
IP address in an Internet Protocol-based
network. A web site is hosted on at least
one web server, accessible via a network
such as the Internet or a private local area
network.
A web page is a document, typically written
in plain text interspersed with formatting
instructions of Hypertext Markup Language
(HTML, XHTML). A web page 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.
All publicly accessible websites
collectively constitute the World Wide Web.
The pages of a website can usually be
accessed from a simple Uniform Resource
Locator (URL) called the homepage. The URLs
of the pages organize them into a hierarchy,
although hyperlinking between them conveys
the reader's perceived site structure and
guides the reader's navigation of the site.
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 journal sites, gaming sites,
message boards, web-based e-mail, services,
social networking websites, and sites
providing real-time stock market data.
