OSI Reference Model: Layer 7 Hardware - TechGenix Data link layer - Wikipedia Windows Network Architecture and the OSI Model It is the second layer of the OSI model. The physical layer is the OSI model's lowest layer, and it's the one nearest to the physical media. The application layer at the top is layer 7 and is closest to the end user. The lower layer of OSI Model mainly deals with the transportation data issues. The Open System Interconnect ( OSI) reference model is a model, developed by the International Standards Organization (ISO), which describes how data from an application on one computer can be transferred to an application on another computer. What is the OSI Model? 7 layers explained in detail At each level N, two entities at the communicating devices (layer N peers) exchange protocol data units (PDUs) by means of a layer N protocol. This layer deals with packet forwarding and sets the route that packets travel through a network. Osi Model Layers, Function, Hardware, Protocols And Standards This layer actually deals with making connection of two distinct station points. It resides in the Application layer of the OSI model. Application Layer The application layer is the closest to the end-user. OSI model was developed by ISO (International Standard organization).
