Layer 5 What layer is the Transport layer? Layer 4 What layer is the Network layer? Layer 3 What layer is the Datalink layer? Layer 2 What layer is the Physical layer? Layer 1 What is the function of the Application layer? Works with specific networking applications such as web browser programs, file transfer programs and email. What is the function of the Presentation layer? *Ensures character code recognition * Responsible for converting character codes into a code that is recognizable by a computer that uses a different code. What is the function of the Session layer? *Establishes a different connection between two different computers - control dialog between source and destination node, which node can send and for how long. *Provides security based on computer and username recognition and handles error processing. What is the function of the Transport layer? *Main responsibility is to ensure reliable data by sequencing packets and reassembling them into their correct order meaning to guarantee the packet will be delivered in the same order sent. *Delivery guaranteed by sending an acknowledgment back to the source when messages are received. What is the function of the Network layer? *Responsible for routing packets from one network to the other using IP addressing format.
