OSI may refer to:
A reference model in systems, enterprise, and software engineering is an abstract framework or domain-specific ontology consisting of an interlinked set of clearly defined concepts produced by an expert or body of experts in order to encourage clear communication. A reference model can represent the component parts of any consistent idea, from business functions to system components, as long as it represents a complete set. This frame of reference can then be used to communicate ideas clearly among members of the same community.
Reference models are often illustrated as a set of concepts with some indication of the relationships between the concepts.
According to OASIS (Organization for the Advancement of Structured Information Standards) a reference model is "an abstract framework for understanding significant relationships among the entities of some environment, and for the development of consistent standards or specifications supporting that environment. A reference model is based on a small number of unifying concepts and may be used as a basis for education and explaining standards to a non-specialist. A reference model is not directly tied to any standards, technologies or other concrete implementation details, but it does seek to provide a common semantics that can be used unambiguously across and between different implementations."
The Open Systems Interconnection model (OSI model) is a conceptual model that characterizes and standardizes the communication functions of a telecommunication or computing system without regard to their underlying internal structure and technology. Its goal is the interoperability of diverse communication systems with standard protocols. The model partitions a communication system into abstraction layers. The original version of the model defined seven layers.
A layer serves the layer above it and is served by the layer below it. For example, a layer that provides error-free communications across a network provides the path needed by applications above it, while it calls the next lower layer to send and receive packets that comprise the contents of that path. Two instances at the same layer are visualized as connected by a horizontal connection in that layer.
The model is a product of the Open Systems Interconnection project at the International Organization for Standardization (ISO), maintained by the identification ISO/IEC 7498-1.

http://www.soundtraining.net/cisco-router-training-101 The OSI reference model provides a means of understanding how data flows from an application on one computer to an application on a different computer. In this I.T. tutorial video, you will be given an introduction to the workings of the OSI model. Author and speaker Don R. Crawley will explain each of the layers from the physical layer to the application layer, including an explanation of Protocol Data Units, protocols, and equipment associated with each layer.

Get Full Course: http://www.engineeringmentor.com/CNYTv1 Networks#2: The "OSI Model" also known as "OSI Reference Model" is discussed here in 2 parts: a) Understanding OSI Reference Model b) OSI Model layers a) Understanding OSI Model (00:22): http://youtu.be/p7UR7Nipqcs?t=22s The OSI reference model is one such communication model. OSI stands for "Open Systems Interconnection" which means that every system participating in this model is open for communication with other systems. This model was first defined by an organization called as ISO. The OSI model divides the communication into 7 layers. b) OSI Model layers (2:15) : http://youtu.be/p7UR7Nipqcs?t=2m15s Quick Look of the 7 layers of the OSI reference Model: 7) Application Layer is where the users interact with applications to pr...

Don't feel like the sun's coming up
Don't feel like it's gonna get better
I can't keep promises
I forget beeing seventeen
Hard times comes to your troubled son
Hope is the last thing that he needs
Hope is a candle that feeds
Off the air till it leaves almost nothing
Gotta stay
Gonna stay
Gonna stay
Can't stay
Hope only got us so far
And the saddest thing
As the wind blows your hair
