Same question on ITPEC: Apr 2024 Q78
Which of the following is the appropriate description concerning an international organization for standardization?
Explanation
ITU, for telecommunications — the International Telecommunication Union is the United Nations agency that sets telecommunication standards.
The ITU, a specialized agency of the United Nations, allocates radio frequencies and satellite orbits and, through its standardization sector ITU-T, issues recommendations for telephone and data networks, such as the X.509 certificate format and H.264 video coding. The other three organizations exist, but each option pairs one with the wrong field.
Answer (d)
Why not others:
- •(a) ICANN — coordinates Internet domain names and IP addresses; standardization across industry, science and technology is the field of ISO
- •(b) IEC — the International Electrotechnical Commission sets standards for electrical and electronic technology, not e-commerce
- •(c) IEEE — the Institute of Electrical and Electronics Engineers sets standards such as IEEE 802.3 (Ethernet) and IEEE 802.11 (wireless LAN); accounting is not its field
Key rule: ISO covers most industrial fields, IEC electrical and electronic technology, ITU telecommunications; IEEE sets LAN and other electronics standards, W3C web standards, and ICANN manages domain names and IP addresses.
