Describe two of the Standards-setting organizational bodies

What will be an ideal response?

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.
