Question

You want to transfer a document from one computer to another, and you want the document to be encrypted. The destination computer is on another network, so you know data has to travel through one or more routers. The network technology on your network is Ethernet, but the technology on the destination network is Wi-Fi. From what you have learned about networking, should this document transfer work? Why or why not? Which layers of the OSI model are involved in the italicized parts of this description?

Explanation / Answer

Answer:

This document transfer should work just fine. Because of the IEEE standards, the presentationlayer will encrypt/decrypt the data on both sides of the network. The session layer establishescoordination between the applications and the transport layer ensures delivery. Once the segments hitthe network, routers handle the routing of the packets to the distant end. Layers 6, 3 & 1 are directlyinvolved in the italicized parts of the question, however, all layers play a part when looking at thetransfer as a whole
