OSI

(1) (Open System Interconnection) An ISO standard for worldwide communications that defines a protocol framework in seven layers. OSI functionality exists in all communications systems, although two or three layers may be incorporated into one (see OSI model). Control is passed from the top application layer to the bottom layer, out over the network to the bottom layer of the receiving station and back up to the application layer.

Never Completely Defined
OSI was too loosely defined to become a single standard. Nevertheless, the model serves to teach communications. Compare TCP/IP, the global standard, with the OSI model (see OSI model and TCP/IP).

(2) (Open Source Initiative) A non-profit corporation dedicated to promoting open source software. The OSI logo on software certifies that it is distributed under one of several approved licenses. For more information, visit www.opensource.org. See open source.


An Approved License
This logo can be used if software is distributed under one of several licenses approved by the Open Source Initiative.
