exponent that describes approximations to
certain non-linear transfer functions encountered in image capture
and reproduction. Within this International Standard, gamma is the
exponent in the transfer function from

From Web
Characterization Terminology & Definitions Sheet (1999-05-24) | Glossary for this

some other server with the purpose of supplying resources or
resource manifestations from that other server. Clients using a
gateway know the gateway is present but does not know that it is an
intermediary.

From Web Services Glossary (2004-02-11)
| Glossary for
this source
An agent that terminates a message on an inbound interface with the intent of presenting
it through an outbound interface as a new message. Unlike a
proxy, a gateway receives messages as if
it were the final receiver for the message. Due to possible
mismatches between the inbound and outbound interfaces, a message
may be modified and may have some or all of its meaning lost during
the conversion process. For example, an HTTP PUT has no equivalent
in SMTP.
Note: a gateway may or may not be a SOAP node; however a gateway is never a
SOAP intermediary, since gateways
terminate messages and SOAP intermediaries relay them instead.
Being a gateway is typically a permanent role, whilst being a SOAP
intermediary is message specific.
