What is an Enterprise Server?

An enterprise server is a computer containing programs that collectively serve the

needs of an enterprise rather than a single user, department, or specializedapplication.

Examples are Sun Microsystems' computers with their UNIX -based Solaris or Linux

systems, Hewlett-Packard ( HP ) systems, the upper end of Windows 2000 systems,

and IBM's iSeries systems (the largest of which is the zSeries 900 -formerly called the

S/390 )

What is an Enterprise Server?

Some companies use enterprise server to describe a "super-program" that

runs under the operating system in a computer and provides services for thesystem administrator and for the business application programs and more

specialized servers that run in the computer. Before this usage originated,

such services were sometimes considered part of the operating system itself

or came in separate software packages.
