midrange

Historically, midrange computers have been sold to small to medium-sized businesses as their main computer and to larger enterprises for branch or department-level operations. Makers of popular midrange computer lines include Hewlett-Packard, IBM, and Sun Microsystems. Today's computers are almost universally known as servers to recognize that they often "serve" applications to end users at "client" computers, that they use a client/server computing model, and, by inference (since the client/server model developed in UNIX-based operating systems), that they support standard rather than proprietary programming interfaces.
