Question
Match each layer in the internet protocal stack with a function; so match A-E with 1-5 and please give a motivation to each match.
A. Application layer
B. Transport layer
C. Network layer
D. Link layer
E. Physical layer
1. Communication between two different computers, including the choice of route through the network. 2. ommunication between two processes on different computers. 3. Communication and coding of data in a way that suits the underlying physical medium. 4. Communication between two programs that together make up a distributed system 5. Communication between two directly connected computers, including adressering if it is a shared mediumExplanation / Answer
A. Application layer ------- Communication between two programs that together make up a distributed system.
Application layer defines application protocols using programs.
B. Transport layer ------- Communication between two processes on different computers.
Transport layer is responsible for allowing devices on the source and destination hosts to carry on a conversation.
C. Network layer ------ Communication between two different computers including the choice of route through the network.
Networking layer is used for routing or moving packets .
D. Link layer ------- Communication between two directly connected computers ,including addressing if it is a shared medium.
Data Link Layer is responsible for addressing . It adds a header to the frame in order to define physical address of the sender or receiver of the frame.
E. Physical layer ------- Communication and coding of data in a way that suits the underlying physical medium.
Physical layer takes care of the coding of data (bits into signals)for physical medium to be used for communication.
