 WWW
- The World Wide Web (commonly shortened
to the Web) is a system of interlinked hypertext documents
accessed via the Internet.
A website
(alternatively, web site or 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.
A Web page
is a document, typically written in HTML, that is almost always
accessible via HTTP, a protocol that transfers information from
the Web server to display in the user's Web browser.
All publicly accessible websites are seen collectively as
constituting the "World Wide Web".
The pages of websites can
usually be accessed from a common root URL called the homepage,
and usually reside on the same physical server. The URLs of the
pages organize them into a hierarchy, although the hyperlinks
between them control how the reader perceives the overall
structure and how the traffic flows between the different parts of
the sites.
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.
Turning a website into an
income source is a common practice for web-developers and
website owners. There are several methods for creating a
website business which fall into two broad categories, as
defined below.
1. Content based sites
Some websites derive revenue by selling advertising space on
the site (see contextual ads).
2. Product or service based sites
Some websites derive revenue by offering products or services.
In the case of e-commerce websites, the products or services
may be purchased at the website itself, by entering credit
card or other payment information into a payment form on the
site. While most business websites serve as a shop window for
existing brick and mortar businesses, it is increasingly the
case that some websites are businesses in their own right;
that is, the products they offer are only available for
purchase on the web.
Guides have been published which explain how to create a
variety of types of websites including those in both the above
categories. See the links at the bottom of this page.
Websites occasionally derive income from a combination of
these two practices. For example, a website such as an online
auctions website may charge the users of its auction service
to list an auction, but also display third-party
advertisements on the site, from which it derives further
income.
