Matching Pairs NETWORKING-3Online version Study OSI Model by Coskun Polat 1 DATA LINK LAYER 2 PHYSICAL LAYER 3 SESSION LAYER 4 NETWORK LAYER 5 PRESENTATION LAYER 6 TRANSPORT LAYER 7 APPLICATION LAYER This layer interacts with an application program, which is the highest level of OSI model. This layer provides the functional and procedural means of transferring variable length data sequences from one node to another connected in "different networks". This layer builds on the network layer to provide data transport from a process on a source machine to a process on a destination machine. This layer transforms data into the form which is accepted by the application. It also formats and encrypts data which should be sent across all the networks. This layer corrects errors which can occur at the physical layer. This layer helps you to define the electrical and physical specifications of the data connection. This layer controls the dialogues between computers. It helps you to establish starting and terminating the connections between the local and remote application.
