9.Consider a particular small business with which you are
familiar (as a customer, as a current or former employee, as a
relative of the owner). Describe the current telecommunications
employed by the business. In what ways might telecommunica-
tions and networking be used to improve the profitability of this
business? Consider, as appropriate, such ideas as the use of
facsimile communication, telemarketing, enhanced communi-
cation through a local area network, a Web home page, accept-
ance of orders over the Web, and smartphones for employees.
10.Discuss the advantages and disadvantages of wireless
communication, such as Bluetooth and wireless LANs,
compared to wired communication. Using your knowledge


and your personal crystal ball, will wireless communication
become more or less important in the future? Why?
11.Cellular telephone service has certainly become more
important vis-à-vis wired telephone service over the past
decade. Will this trend continue? How will the trend toward
cellular service be affected by other developments in
telephony such as massive increases in bandwidth through
fiber-optic technology and the wider use of telephony over
the Internet?
12.Explain, in your own words, the concept of cloud computing.
Do you believe that cloud computing will have a major
impact on the IT function in organizations? Why or why not?
In your opinion, what are some factors that will hold back the
growth of cloud computing?
