an outline of the steps she would follow in using the
topics. For example, she would need to check the topics,
and use them at her desk.
b.
Suppose the student is working on a paper of moderate
size, for which she wants to use seven topics from the
library. Again, write an outline of what steps she might fol
low in using the topics. Remember that only two topics can
be open on her desk at one time.
c.
Suppose the student wants to consult 12 topics for a large
paper. Again, write an outline of what steps she might fol
low. Even using both her desk and her bookshelf, her dorm
room can store only 10 topics.
d.
Suppose the student wishes to work on all three papers, for
parts a, b, and c at once. After doing some work on one
paper, she wants to put it aside and think about it while she
works on the other papers. Again, outline how she might
proceed in using the topics while she makes progress on the
three papers.
e.
Compare the work of the student in parts a through d with
the workings of a computer. To what extent does the model
of student activity have an analog to the CPU, registers,
cache memory, or main memory? Are there any ways in
which this analogy breaks down? Explain your answer.

When a customer calls a service technician regarding a prob
lem with a television set, the technician travels to the cus
tomer's home. The technician keeps a collection of commonly
used tools in her truck, and uses these as needed in trou
bleshooting the problem. Often, the technician can fix the
problem during the initial call. However, sometimes the tech
nician must take the television set to the shop for more exten
sive repairs. And sometimes the technician must order parts
from a factory or warehouse before the problem can be fixed.
To what extent does this hierarchy of equipment and service
(house, tools in truck, equipment in shop, parts from a ware
house) correspond to the storage of data within a computer?
Explain any similarities and clarify any differences.
