OSI 7 Layer reference model, more information ...
Open Systems Interconnection reference model. A framework developed by the International Standards Organization (ISO) to provide worldwide standards for computer communications.
Open Systems Interconnection model The standard for transmitting messages between any two points in a network. Its purpose is to guide product developers so that their products will consistently work with other products. The model defines seven layers of functions that occur at each end of a communication link: 7--application, 6--presentation, 5--session, 4--transport, 3--network, 2--data link, and 1--physical.
The 7-layer protocol model defined by the International Standards Organization (ISO) for data communications.
The Open System Interconnection model that defines a networking framework divided into seven layers: Pyhsical, Datalink, Network, Transport, Session, Presentation and Application. Instructions move from one layer to the next. In communcations from one computer to another, data starts with the user interaction with the Application layer moves down the seven layers, across a physical connection and back up the layers at the destination device.
A model for how networks should transmit data from point to point, using 7 layers to describe different stages of preparing (or "encapsulating") data for transmission. The seven layers are: Application Presentation Session Transport Network Data Link Physical IEEE 802.11 wireless specifications pertain to the Physical and Data Link layers. Back
Open Systems Interconnection Reference Model commonly known as OSI Model describes seven layers Physical Layer, Data Link Layer, Network layer, Transport layer, Session layer, Presentation layer and Application layer.
The seven-layer OSI Reference model was developed by the ISO subcommittee. The OSI model serves as a logical framework of protocols for computer-to-computer communications. Its purpose is to facilitate the interconnection of networks.
Open Systems Interconnect Model. You need to memorise this to pass one of the Microsoft exams. I have never met anyone that can actually understand it. This is because it is all nonsense. Application Layer Interfaces with applications providing high-level networking services (such as named pipes). Presentation Layer Converts and translates (if necessary) information. Session Layer Maintains a bi-directional communication connection between two computers. Transport Layer Guarantees delivery of packets. Network Layer Creates a path between two computers via routed packets. Transport protocols implement both the Network layer and the Transport layer. Data-Link Layer Provides digital interconnection of networks devices and the software that directly operates these devices. (such as NICs) Also known as the Media Access Control Layer Physical Layer The cables, connectors and ports.
The Open Systems Interconnection Model is a way of representing the complexities of computer networking in a seven layer model, ranging from the physical hardware of networking, all the way up to how application programs talk to the network. The seven layers are: physical, data link, network, transport, session, presentation and application. The seven-layer OSI model can be used to help diagnose network problems.
The Open Systems Interconnection (OSI) reference model for describing network protocols was devised by the Internet Standards Organization. It divides protocols in to seven layers to standardize and simplify definitions.
Contains 7 layers that provide a framework for communication of dissimilar networking systems.
A concept developed by ISO and CCITT used to develop standards for data networking that promote multivendor equipment interoperability. The OSI model is separated into seven layers that relate to the interconnection of computer systems. See also application layer, presentation layer, session layer, transport layer, network layer, data link layer, and physical layer.
A model which many networking terms and protocols are referenced against; very useful when discussing networking. A brief explanation of the 7 Layers of the OSI Model can be found on Webopedia.com. The more familiar you are with the OSI layer the easier it is to converse with computer networking people.

A reference model developed by the ISO. The OSI model provides an accepted framework of standards for communication between different systems and vendors. In short, the model organizes the communications process into seven different categories. Layers 1 through 3 deal with network access. Layers 4 through 7 deal with end-to-end communications between the message source and the message destination.
seven-layer model of network communications developed by the International Standard Organization (ISO).
A seven-layer logical network architecture that is used for the definition of network protocol standards to enable an OSI compatible computer or device to communicate with any other OSI-complaint computer or device for a meaningful exchange of information. Layer 7, the application layer, is responsible for exchanging information between the programs that are running on a computer and other services on a network. Layer 6, the presentation layer, formats information so that a software application can read it. Layer 5, the session layer, supports connections between sessions and handles administrative tasks and security. Layer 4, the transport layer, corrects transmission errors and ensures that the information is delivered reliably. Layer 3, the network layer, identifies computers on a network and determines how to direct information transfer over that network. Layer 2, the data-link layer, groups data into containers to prepare that data for transfer over a network. Layer 1, the physical layer, defines how a transmission medium connects to a computer, as well as how electrical or optical information is transferred on the transmission medium.
The Open Systems Interconnection Basic Reference Model (OSI Reference Model or OSI Model for short) is a layered, abstract description for communications and computer network protocol design, developed as part of the Open Systems Interconnection initiative. It is also called the OSI seven layer model.
