ISO Network Model
A network model developed by the International Standards Organization (ISO) that consists of seven different levels, or layers. By standardizing these layers, and the interfaces in between, different portions of a given protocol can be modified or changed as technologies advance or systems require- ments are altered. The seven layers are:
•Application, Layer 7
•Presentation, Layer 6
•Session, Layer 5
•Transport, Layer 4
•Network, Layer 3
•Data Link, Layer 2
•Physical, Layer 1
