Today, we continue our investigation of all the complex communications systems that lie invisibly beneath our day-to-day life. This morning's lesson is particularly technical, so hold onto your hat and try to keep up!
  1. Explain the need for the varying levels in communications systems.
  2. Explain why each level tends to need its own protocol(s).
  3. In detail, describe the actions that take place on each level.
