my question is :

The network was designed using a layered architecture. Each layer has a specific function or task to support its upper layer. The collection of these specifications is called a protocol stack or suite.

 

Complete the following table by first arranging the tasks in order from the upper layer to the lowest layer. Then identify the layer names, then common network devices associated with those layers, and describing typical standard protocols used in the stack.

 

The given tasks (to be correctly reordered in the table by the student) for the given layers are:

• Determines the path that messages take between clients and server over the network
• Transmit and receive data frames
• Ensures that the information sent by a server reaches a client
• Permit a client-side file transfer software and the file server software to understand messages sent between them

 

Your answer:
