1. <networking> A deprecated term for a device that enables
data to flow between different networks (forming an
internet).
Preferred terms are "protocol converter" (connects networks
that use different protocols), "router" (connects two
broadcast networks at layer 3 (network layer). Another
example is a mail gateway, which is a layer 7 (application
layer) gateway.
2. <hypertext> An interface between an information source
and a World-Wide Web server. Common Gateway Interface
is a standard for such interfaces. The information source
can be any system that can be accessed by a program running on
the web server. A typical example is a relational
database.
