Spring 2012
Homework No. 2
Due Date: Friday, February 10, 2012
Reading: Chapters 3, 4 (Complete review of TG 1)
(1) Knowledge Questions: Know the answers, but do not submit through BB (BlackBoard.)
Your answers will be based on your reading, review, and class discussions.
1) What is your opinion about the ethical issues encountered by NASA (3rd ed., pp. 72-7)?
Structure your answer along the four ethical categories related to computing.
2) For the CheckFree case (p. 94), both CheckFree and Network Solutions were involved. How
can the two companies, working together, prevent further attacks?
3) Describe several physical threats and several non-physical threats to information related to (i)
privacy; (ii) security.
4) Explain the benefits of IT auditing and planning for cases of disaster recovery.
5) Understand the data life cycle (Fig. 4.1) and illustrate it for (a) e-book; (b) financial
information system.
6) Lab-based questions:
a. Explain and illustrate each of the three main functions of CAD models based on what you
applied during labs 1 and 2.
b. What are three methods to create a solid model in AutoCAD?
c. Why is it helpful to have the same Grid spacing as the Snap spacing?
d. If the plot scale of the facility layout in Lab is 1 inch : 16 feet, what are the base and
height of the triangle area on a printout of your drawing?
e. Describe two benefits for designers of using layers in AutoCAD. Illustrate each benefit
with an example in your labs. Then relate your answers to PLM.
f. Describe three methods used to create 3D objects from 2D objects. Which methods have
you used (or could use) during Lab 2 to create which 3D objects?
g. Explain which one or more technologies out of CAD, CAM, CAE, or rapid prototyping
has/have been applied to perform each of the following tasks:
(i) Using software to test the strength and determine the materials of a desk before
production.
(ii) A CNC (Computer Numerically Controlled) machine can cut 3D objects according to
CAD design by converting design data to manufacturing data.
(iii) After performing a two-hour fatigue on test a car-door with computer software, a test
company concludes that the designed lifetime of the car-door is 11 years.
(iv) To design cardboard packing boxes, a software package is used to create a database
of standardized cutting templates.

(one from each chapter) that an ICT project might fail?
2. For the case of New York Life (3rd ed. pp. 67-9):
(i) Why was a portal solution effective in addressing each of the three problems?

(iv) How are several problems associated with legacy (old computing technologies) systems
solved by the portal solution?
(v) What are some examples of information security that threaten this solution approach?
3. What are six typical difficulties with data management, and how do database management
systems solve them? Illustrate your answer based on the university DBMS (Fig. 4.2).
