Portal

An entrance, gate, or door to a building or courtyard, often decorated; it marks the transition from the public exterior to the private interior space.

Portal

 

in architecture, an opening, usually an entrance into a building. Typical ancient Egyptian and ancient Greek portals were simply ornamented and had level crosspieces. In ancient Mesopotamia portals were arched, and in the Near and Middle East peshtak portals were typical; these were rectangular and had a cut-out lancet arch. Beginning in the 11th century arched, or perspective, portals became widespread in romanesque, gothic, and ancient Russian architecture. These portals were projections whose corners had columns joined by archivolts. Renaissance and baroque portals usually had pilasters and columns that supported the entablature or frontal.

portal

(World-Wide Web)
A website that aims to be an entry point to the World-Wide Web, typically offering a search engine and/or links to useful pages, and possibly news or other services. These services are usually provided for free in the hope that users will make the site their default home page or at least visit it often. Popular examples are Yahoo and MSN. Most portals on the Internet exist to generate advertising income for their owners, others may be focused on a specific group of users and may be part of an intranet or extranet. Some may just concentrate on one particular subject, say technology or medicine, and are known as a vertical portals.

portal

A Web "supersite" that provides a variety of services including Web search, news, blogs, discussion groups, shopping and links to other sites. The major general-purpose portals are Yahoo, MSN and AOL, all of which offer free Web-based e-mail accounts. TV networks and newspapers provide general-purpose portals, but not e-mail. Many portals allow the home page to be personalized (see personal portal). Prior to the Web, CompuServe and AOL functioned as portals, aggregating information from various sources.

The Vortal
Portals also serve vertical markets. Trade magazines, associations and special interest groups host vertical portals (vortals) and provide news and articles for their industry such as IT, banking and insurance. The vortal may also include general information such as top news stories and weather; however, their search capabilities are often limited to their own archives, rather than the entire Web. See corporate portal, business intelligence portal and portal server.
