Answer:
1. First, an agreement, or protocol, must specify how the data are to be packaged, or formatted,
so that they can be sent between sending and receiving devices.
2. The ability of the communicating devices to understand the formatting protocols being used.
3. A third characteristic that data communication protocols should address is the speed of the
communication
4. When two devices need to communicate, one of the devices may not be available for a variety
of reasons: hardware failure, a downed communication link, system repair, or software
upgrading.

9) Describe two of the Standards-setting organizational bodies.
Answer: The ITU-T concerns itself with international telecommunications issues. The ITU-T's
particular areas of interest are phone and data systems. The ITU-T has established standards that
define data transmission over phone lines, e-mail and directory services, and transmission over

public digital networks.
ANSI represents the United States on the ISO. However, ANSI does not have a formal affiliation
with the Federal Government; it is a nonprofit, private corporation. ANSI's membership list
includes industry associations, consumer groups, governmental bodies, professional associations,
and other interested parties. ANSI is the principal standards-setting body in the United States.
The IEEE defines many standards for both local area networks (LANs) and backbone networks
(BNs). Emphasizing electronics and electrical engineering, the IEEE is the world's largest
professional engineering society. The IEEE is playing a critical part in establishing new wireless
communication standards. (See this chapter's "Topic in Focus" to find out more about the IEEE.)
The TIA is a nonprofit organization accredited by the American National Standards Institute
(ANSI) to develop voluntary industry standards for a wide variety of telecommunications
products. The TIA plays a fundamental role in the defining of standards for electrical and
functional characteristics of interface equipment.

10) What is the main purpose of the ISO (International Standards Organization)?
Answer: The ISO is an international body of voluntary organizations with great influence in the
field of information technology. The ISO attempts to create international technological
compatibility by supporting and establishing worldwide standards.
