  2. Describe the solution devised by Alexander Graham Bell. 
  3. Define coaxial cable and explain the ways that it is superior. 
  4. Explain how fiber optic cables avoid these problems altogether - and account for the fact that fiber optic cables have not become the dominant type of cable used in networks.
