OSI layer contains all protocols and methods

Hi,

All protocols and methods that fall into the realm of process-to-process communications across an Internet Protocol (IP) network are part of the Application Layer of the OSI(Open System Interconnection) model.

Application layer handles issues like synchronizing communication, checking the transparency of the network, checking if the resources are available or not for the communication.

It manages the communication between different running processes and applications. Privacy and syntax or constraints for data transfer are also identified in this layer. It ensures error recovery procedures and  privacy on both ends of the network. It is not an application instead it is a service layer. The programs that use this layer are called applications processes.

It is top layer of OSI model.

OSI layer contains all protocols and methods

OSI stands for Open Systems Interconnection model. It is an abstract model that distinguishes and regulates the internal functions of a communication system by dividing it into abstraction layers. This is the result of the Open Systems Interconnection project at the International Organization for Standardization or ISO. The idea of a seven-layer model was given by the effort of Charles Bachman of the Honeywell Information Services.

There are seven layers,and each layer is typically identified as an N layer. First layer is Physical. This is a somewhat dependable straight point-to-point data connection. Second layer is Data link. This is a reliable direct point-to-point data connection. Third layer is Network. The addressing, routing, and distribution of diagrams among points on a network are sometimes reliable.

Fourth layer is Transport. Here, you can expect a consistent distribution of packets among points on a network. Fifth layer is Session. It works as an interhost communication and handling sessions between applications. Sixth layer is Presentation. This is for data representation, encryption and decryption, and conversion of machine-dependent data to machine-independent data.

The seventh and final layer is Application. This is for network process to application.
