CHAPTER 1: DATA COMMUNICATIONS, DATA NETWORKS,
AND THE INTERNET
UV
TRUE OR FALSE
T F 1. Data communications deals with the transmission of signals in a
reliable and efficient manner.
IA
T F 2. There are several fundamental differences between data
processing and data communications.
_A
T F 3. There are no fundamental differences among data, voice, and video
communications.
T F 4. Effective and efficient data communication and networking
facilities are vital to any enterprise.
PP
T F 5. Growth in services and growth in traffic capacity go hand in hand.
T F 6. The increasing use of optical fiber, while greatly increasing
capacity, has caused an increase in transmission prices as well.
RO
T F 7. Convergence refers to the merger of previously distinct telephony
and information technologies and markets.
T F 8. Changes in corporate data traffic patterns are driving the creation
of high-speed WANs.
VE
T F 9. It is not necessary for a device to interface with the transmission
system in order to communicate.
D?
T F 10. A modem is required to establish communication between a
workstation and a server over a public telephone network.
T F 11. Compression refers to the ability of a number of devices to share a
transmission facility.
??
T F 12. The basic building block of any communications facility is the
transmission line.
T F 13. Developing switching systems with the capacity and rapid
??
response to support the demand requirements with the increased
use of fiber optic transmission is no longer a challenge.
