Web server A computer that delivers Web pages to browsers and other files to
applications via the HTTP protocol.

It includes the hardware, operating system, Web server software, TCP/IP
protocols and site content (Web pages and other files).

If the Web server is used internally and not by the public, it may be called an
"intranet server." before the Web, the term referred to a computer in a
client/server environment that performed the business logic (the data
processing).

In a two-tier client/server environment, which is most common, the user's
machine performs the business logic as well as the user interface, and the
server provides the database processing.

In a three-tier environment, a separate computer (application server) performs
the business logic, although some part may still be handled by the user's
machine.

The application server may reside in the same computer as the Web server (HTTP
server) or be in a separate computer.

In large sites, multiple computers are used for both application servers and Web
servers (HTTP servers).

Examples of Web application servers include BEA Weblogic Server and IBM's
WebSphere Application Server.
