to davelop its open sytem interconnection (ISO) network suit.
ISO has two major component; an abstract model of networking (the basic reference model, or seven major model) and set of concrete protocol. the standard documents the describe ISO area for sale and not currently available online. parts of ISO have influenced internet protocol development, but more than the abstract model itself, documented in ISO 7498 and its various added. in this model, a networking

OSI seven-layer model
http://catalyst.washington.edu/help/computing_fundamentals/networking/img/osi_model.jpg
The seven Layers Described
• Physical layer: The lowest layer of the model, it provides the transmission of data. This layer defines electrical and mechanical properties. for example: kani na layer magpahibalo sa kadaku sa ethernet coaxial cable, ang klase sa BNC connector magamit, and the termination method.
• Network layer: The third layer routes data from one network node to others. for example: kini na layer nagpahibalo sa addressing and routing structure sa internet.
• Transport layer: This layer ensures that data from the source arrives at the destination correctly and in proper sequence. for example: ani la layer magpahilbalo kung or unsa retransmission ang gigamit to ensure ang data paghatud.
• Session layer: The layer provides the capability for cooperating applications to synchronize and manage their dialog and data exchange. for example: nag pahibalo gi unsa pag request ug pag reply sa packet are paired in a remote procedure call.
• Presentation layer: This provides services that interpret the meaning of the information exchanged. for example: nagpa ila gi unsa pag flaoting point number can be exchange between host with different math formats.
• Application layer: This layer directly serves the end user. It supports end applications such as file transfer and database access. for example: ang layer gusto ipasabot anf file system operations.
