Telephone is a classic kids game where the first person in lineis told a message. That person whispers the word to the one next tothem, and so on. The last person in line then announces the messageas they understand it.
Describe this game as a networking protocol in terms of the OSImodel. Be specific, and include whatever layers you see asimportant.
How could you change the protocol (and ruin the game) to ensurethat the message reached the destination unaltered? Again, answerthis in terms of the OSI layers.
