Do you see yourself using email in the not-too-distant future? The path of an email message starts with the sender and concludes with the receiver of the message. Take careful notes on everything you discover. Is there a rationale to the differences, and if so, what are they? Consider the possibility that there exist several models, each of which has a unique level of complexity (or abstraction).
Take, for example, the impact that the introduction of the personal computer and the World Wide Web has had on the design of the system. Make sure that your claims are supported by proof whenever it is possible to do so.
That is the man or woman who came up with the idea of ADTs? Describe them. How are they put into practise? In what ways are ADTs more advantageous than traditional methods? Does the idea of heredity make it simpler to deal with problems?
Imagine email in your own words. If I send a message through email, how does it go from my computer to theirs? Make a tally of everything you've unearthed.
