As a WAN protocol, Frame Relay is most commonly implemented at Layer 2 ( data link layer ) of the Open Systems Interconnection ( OSI ) seven layer model.

The protocol was defined in ISO / IEC 10589: 2002 as an international standard within the Open Systems Interconnection ( OSI ) reference design.

Open Systems Interconnection ( OSI ) is an effort to standardize networking that was started in 1977 by the International Organization for Standardization ( ISO ), along with the ITU-T.

CMIS is part of the Open Systems Interconnection ( OSI ) body of international network standards.

FDDI, as a product of American National Standards Institute X3T9. 5 ( now X3T12 ), conforms to the Open Systems Interconnection ( OSI ) model of functional layering of LANs using other protocols.

The Open Systems Interconnection model ( OSI model ) is a product of the Open Systems Interconnection effort at the International Organization for Standardization.

In telecommunication, a n-entity is an active element in the n-th layer of the Open Systems Interconnection -- Reference Model ( OSI-RM ) that ( a ) interacts directly with elements, i. e., entities, of the layer immediately above or below the n-th layer, ( b ) is defined by a unique set of rules, i. e., syntax, and information formats, including data and control formats, and ( c ) performs a defined set of functions.

The Open Systems Interconnection Specification ( OSI )- refers to the use of the specifications laid out in the OSI reference model.

The Open System Interconnection ( OSI ) reference model was developed under the auspices of the International Organization for Standardization ( ISO ) and provides a rigorous description for layering protocol functions from the underlying hardware to the software interface concepts in user applications.

Considering the urgency of the need for standards which would allow constitution of heterogeneous computer networks, ISO created a new subcommittee for " Open Systems Interconnection " ( ISO / TC97 / SC 16 ) in 1977.

" This paper presents the model of architecture for Open Systems Interconnection developed by SC16.

After this Eric Raymond and Bruce Perens founded the Open Source Initiative ( OSI ), to promote the term " open-source software " as an alternative term for free software.

This was also used by Open Source Initiative ( OSI ) under the name " The Open Source Definition ", the only change being that use of the term " free software " was replaced by OSI's alternative term for free software, " open-source software ".

One popular set of free open-source software licenses are those approved by the Open Source Initiative ( OSI ) based on their Open Source Definition ( OSD ).

The Open Source Initiative ( OSI ) is an organization dedicated to promoting open source software.

They also established the Open Source Initiative ( OSI ) as a steward organization for the movement.

Some critics have claimed that its BanksterUSA site has received $ 200, 000 in funding from the Open Society Institute, the charity with ties to investor George Soros, but its BanksterUSA project was not funded by OSI.

Open systems architecture may be implemented using the OSI Model as a guide while designing the system to meet performance requirements.

The OSI Open Source Definition and the Debian Free Software Guidelines specifically allow for restrictions on distribution of modified source code, given explicit permission to distribute both patches and source code.

XNS predated and influenced the development of the Open Systems Interconnection ( OSI ) networking model.

* Open source, a software development model

" We deliberately used free software as a model ," said Wendy Seltzer, who took over Open Law when Lessig moved to Stanford.

Open systems architecture, in telecommunication, is a standard that describes the layered hierarchical structure, configuration, or model of a communications or distributed data processing system that:

This property places ARP into the Link Layer of the Internet Protocol Suite, while in the Open Systems Interconnection ( OSI ) model, it is often described as residing between Layers 2 and 3, being encapsulated by Layer 2 protocols.

From an Open Source software providers perspective there is the model of open core which includes a feature-limited version of the product and an open core version.

The town uses an Open Town Meeting model with a Board of Selectmen overseeing the operation of the town.

Grosse Ile's Open Space program is considered to be a national model for market-based growth management in a small town.

Transport layers are contained in both the TCP / IP model ( RFC 1122 ), which is the foundation of the Internet, and the Open Systems Interconnection ( OSI ) model of general networking.

* Distributed transaction processing, in computer systems, usually refers to the X / Open model of co-ordinating transactions between multiple participants

The Internet protocol suite ( TCP / IP ) and the Open Systems Interconnection model ( OSI model ) of computer networking each specify a group of protocols and methods identified by the name application layer.

Standards developed jointly with ISO such as ISO / IEC 26300, Open Document Format for Office Applications ( OpenDocument ) v1. 0 carry the acronym of both organizations.

On 6 January 2005, and later again on 25 June 2010, ISO re-affirmed its MUMPS-related standards: ISO / IEC 11756: 1999, language standard, ISO / IEC 15851: 1999, Open MUMPS Interconnect and ISO / IEC 15852: 1999, MUMPS Windowing Application Programmers Interface.

The development of the POSIX standard takes place in the Austin Group, a joint working group linking the Open Group and the ISO organization.

These recommendations were adopted by T. C97 at the end of 1979 as the basis for the following development of standards for Open Systems Interconnectlon within ISO.

ISO was a partner in developing the standards, incorporating them into the Open Systems Interconnection suite of protocols.

POI supports the ISO / IEC 29500: 2008 Office Open XML file formats since version 3. 5.

The current version of the API, ODBC 3. 52, incorporates features from both the ISO and X / Open standards ( see below ).

The X / Open CLI interface is a superset of the ISO SQL CLI.

Doug Mahugh-while working for Microsoft ( a promoter of Office Open XML, a Microsoft document format competing with OASIS's ISO / IEC 26300, i. e. OpenDocument ) as a Senior Product Manager specializing in Office client interoperability-claimed that many countries have expressed frustration about the pace of OASIS's responses to defect reports that have been submitted on ISO / IEC 26300 and the inability for SC 34 members to participate in the maintenance of ODF.
