ISO (International Standards Organization) Network Model
1. Developed by the International Standards Organization, the ISO network model specifies seven layers of communications protocol. Standardizing these layers and the interfaces in between them makes it possible to modify different portions of a given protocol as technologies advance or systems requirements change while maintaining a stable general protocol model. The seven layers are:
* Physical
* Data Link
* Network
* Transport
*Session
* Presentation
* Application
The 802.11 standard encompasses the physical layer (PHY) and the lower portion of the data link layer. The lower portion of the data link layer is often referred to as the Media Access Control (MAC) sublayer.
