Software that provides services to access the Internet, an intranet, or an extranet. A Web server hosts Web sites, provides support for HTTP and other protocols, and executes server-side programs (such as CGI scripts or servlets) that perform certain functions. In the J2EE architecture, a Web server provides services to a Web container. For example, a Web container typically relies on a Web server to provide HTTP message handling. The J2EE architecture assumes that a Web container is hosted by a Web server from the same vendor, so it does not specify the contract between these two entities. A Web server can host one or more Web containers.

Office SharePoint Server 2007 provides a single integrated platform to manage intranet, extranet,
and Internet applications across the enterprise.

An internet site is a normal site that anyone on the internet can access (e.g., www.msn.com, www.
microsoft.com, etc.). You can set up a site for your company that can be accessed by anyone
without any user name and password.
An intranet (or internal network), though hosted on the Web, can only be accessed by people who
are members of the network. They need to have a login and password that was assigned to them
when they were added to the site by the site administrator.

The portal components of Office SharePoint Server 2007 include features that are especially
useful for designing, deploying, and managing enterprise intranet portals, corporate Internet Web
sites, and divisional portal sites. The portal components make it easier to connect to people within
the organization who have the right skills, knowledge, and project experience.

(Look for an answer that involves the word "intranet.")
