Open Systems Interconnection (interconnexion de systèmes ouverts)
Open Systems Interconnection. A framework of the International Organization for Standardization (ISO) standards for communication between different systems made by different vendors, in which the communications process is organized into seven different categories that are placed in a layered sequence based on their relationship to the user. Each layer uses the layer immediately below it and provides a service to the layer above. Layers 7 through 4 deal with end-to-end communication between the message source and destination, and layers 3 through 1 deal with network functions.

(Open System Interconnection) The International Standards Organization's model for standards-based networking.
An ISO standard for worldwide communications that defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, proceeding to the bottom layer, over the channel to the next station and back up the hierarchy. At one time, most vendors agreed to support OSI in one form or another, but OSI was too loosely defined and proprietary standards were too entrenched. Except for the OSI-compliant X.400 and X.500 e-mail and directory standards, which are widely used, what was once thought to become the universal communications standard now serves as the teaching model for all other protocols. Most of the functionality in the OSI model exists in all communications systems, although two or three OSI layers may be incorporated into one. OSI is also referred to as the OSI Reference Model or just the OSI Model.
Open Systems Interconnection. OSI model is a 7-layer protocol stack model that describes procedures for data transfer in a network. It was defined by the ISO. The OSI model has been used as a guideline for network designers and manufacturers in developing network products that guarantee interoperability among various technologies. However, the networking industry doesn't strictly follow the OSI model. For instance, functions that relate to several layers in the OSI model may be performed by one protocol in a particular network technology. The OSI model defines how one layer interacts with another layer in the 7-layer protocol stack. When two computers communicate, information is sent down through the protocol stack to the physical layer (e.g. cable), and travels up through the protocol stack to the application layer for processing by the receiving computer. Below are the layers in the OSI model
(Open Systems Interconnection) This is the evolving international standard under development at ISO (International Standards Organization) for the interconnection of cooperative computer systems. An open system is one that conforms to OSI standards in its communications with other systems.

The OSI reference model is a formal method for describing the interlocking sets of networking hardware and software used to deliver network services. It is a good model, but strict compliance to the model is seldom accomplished.
A model developed by the International Organization for Standardization (ISO) for communications. OSI offers a standard, modular approach to network design that divides the required set of complex functions into manageable, self-contained, functional layers. These layers, starting from the innermost, are: 1. Physical layer — concerned with the mechanical and electrical means by which devices are physically connected and data is transmitted. 2. Data link layer — concerned with how to move data reliably across the physical data link. 3. Network layer — provides the means to establish, maintain and terminate connections between systems. Concerned with switching and routing information. 4. Transport layer — concerned with end-to-end data integrity and quality of service. 5. Session layer — standardizes the task of setting up a session and terminating it. Coordinates the interaction between end application processes. 6. Presentation layer — relates to the character set and data code that is used, and to the way data is displayed on a screen or printer. 7. Application layer — concerned with the higher-level functions that support application or system activities.
