The Transport layer is responsible for taking a message that is too long and breaking it into smaller segments to send out. The reverse is also true, when the information is received the Transport layer is responsible for taking a series of short segments and putting them together again. Hope this helps.
The layer converting segments into fragments by means of packets is called Network layer.

Data Link
The interface between the physical layer and the network link layer.
The three layers of the OSI standard are application layer, transportation and Network layer. Network layer provides the electrical and mechanical interface to network medium, network layer handles routing and forwarding of data. The transport layer ensures data is successfully sent and received between two nodes..
No, this is a common misconception. The application layer is the interface between programs (applications) and the network layers.
The layer of the OSI model provides connectivity and path selection between two end systems where routing occurs in the network layer. The layer of the OSI model provides network services to processes in electronic mail and file transfer programs is application.

Network Interface Layer
Application layer is designed to convert user data to language that can be understood by Presentation layer. For instance, http is at Application layer and converts people language to language that can be understood by browsers.
Router is a Layer 3 (Network Layer)device that checks packet's IP Address at input interface & routes them to interface connected to destination network if available.
Network Layer
signaling
The INTERNET LAYER of OSI model exists for "routing" and providing a single network interface to the upper layers.
