These functions ensure that information sent from application layer of one system will be readable by the application layer of another system. Some examples of the presentation-layer coding and conversion schemes include common data representation formats, conversion of character representation formats, common data compression schemes, and data encryption schemes. This layer interacts with software applications that implement a communication component. Application-layer functions typically include identifying communication partners, determining resource availability, and synchronizing communication. The OSI model provides a conceptual framework for communications between computers, but the model itself is not a method of communication.
Actual communication is made possible by using communication protocols.
The OSI model is considered the primary architectural model for intercomputer communications. Information being transferred from a software application in a computer to a software application in another must pass through each of the OSI layers. At the Physical layer, the data is sent. Each layer encapsulates the data as its goes down the layers. Miguel Hidalgo is a Sr.
