  1. The OSI protocol stack is structured into seven conceptual layers. The layers form a hierarchy of functionality starting with the physical hardware components to the user interfaces at the software application level. Each layer receives information from the layer above, processes it and passes it down to the next layer.

    What layer of OSI model does IP operate?

    The OSI model helps users and operators of computer networks:

    • Determine the required hardware and software to build their network.
    • Understand and communicate the process followed by components communicating across a network.
    • Perform troubleshooting, by identifying which network layer is causing an issue and focusing efforts on that layer.

        Jan 27, 2008 · The TCP/IP Stack and the OSI Model. In the previous section, we learned that TCP/IP is a suite of protocols and rules. It allows us to communicate with other computers and devices over a connection oriented network. What we didn’t cover was the TCP/IP and OSI model- which helps us understand the TCP/IP suite in a manner of layers and modules.
