An Analogy: the Telephone Network
- Let's use an analogy: think about the
telephone system!
Let's suppose you only know about the
copper wire and the
telephone.
- How do
you make a communication network?
- How do you
get phone calls
in your home?
- How do you
get your neighbour a
phone line?
- How can a company
get several different phone calls at
the same time?
- How can you
redirect a
phone call to
a different location?
Obviously, you need more than
copper wires and telephones!
What else would you need?
Enter one noun.
