Sometimes a problem arises with just a small section of a disk
(e.g., with one sector).
a.
Identify a circumstance under which trouble with a single
sector could affect reading of all files on the disk.
b.
Identify a circumstance under which trouble with a single
sector could affect the reading of some files, but not others.
c.
Identify two circumstances under which trouble with a sin
gle sector could affect reading just the very last part of a
file.
d.
Could trouble with a single sector affect the reading of all
data in a single file? Explain.
4.
ROM, or readonly memory, is prepared at time of manufac
ture, so it contains specific data or program information.
While ROM cannot be changed, a computer can read and use
the information. Sometimes one hears stories of writeonly
memory (WOM). The idea would be that a computer could
send data to WOM, but this information then could not be
retrieved. Explain why WOM is not considered useful and
thus is not be manufactured or used.
5.
Some have defined a weed, in gardening, as any plant that is
growing in a place it is not wanted. Discuss how a virus in a
computing environment is similar or different from a weed in
an agricultural environment. (Find at least two similarities
and at least two differences.)

The Association for Computing Machinery (ACM) is the
largest professional society for the computing community.
The ACM home page is
www.acm.org.
a.
Using the search capability from this Web page, locate the
ACM Code of Ethics. Does this Code of Ethics mention the
development of virus programs? If so, what does it say?
b.
Review the application form for ACM professional mem
bership and for ACM student membership. To what extent
does ACM membership commit an individual to acting re
sponsibly (e.g., not developing computer viruses)?
7.
Consider the following scenario (based on actual cases): An
individual discovers a way to circumvent a computer's secu
