解説

問 19

Incorrectア
ICANN (The Internet Corporation for Assigned Names and Numbers) is a nonprofit organization that manages the allocation of IP addresses and domain names; it is not an academic society that carries out LAN standardization.
イ
正解 The correct answer is イ “IEEE”. IEEE (the Institute of Electrical and Electronics Engineers) is a U.S. academic society made up of engineers in the electrical, electronic, and information fields, and it promotes LAN-related standardization. Ethernet LANs are standardized as “IEEE 802.3” and wireless LANs as “IEEE 802.11”, and both are standards developed by IEEE. Therefore, the U.S. academic society referred to in the question is IEEE.
Incorrectウ
ISO (the International Organization for Standardization) is an international body composed of the national standards organizations of various countries; it is not any specific country’s “U.S. academic society”. Moreover, the entity that actually developed the LAN specifications is IEEE.
Incorrectエ
W3C (the World Wide Web Consortium) is an organization that standardizes WWW (Web)-related technologies such as HTML and CSS; its scope differs from the standardization of Ethernet or wireless LANs.

ここがポイント

IEEE is a U.S. academic society that promotes the standardization of LAN specifications such as Ethernet LANs (IEEE 802.3) and wireless LANs (IEEE 802.11).
Distinguishing the roles of standards bodies: ICANN = manages IP addresses/domain names, ISO = International Organization for Standardization, W3C = standardization of Web technologies.
