ITU

ITU stands for International Telecommunication Union, a specialized agency of the United Nations that coordinates global telecommunications standards and spectrum management. The organization traces its origins to 1865, when the International Telegraph Union was formed to facilitate telegraph communication. It adopted the name International Telecommunication Union in the early 20th century, and in 1947 joined the United Nations system as a specialized agency. ITU is headquartered in Geneva, Switzerland, and operates with a network of regional offices and study groups. It is organized into three sectors: ITU-R (Radiocommunication), ITU-T (Standardization), and ITU-D (Development). Collectively, these sectors develop international standards, allocate and harmonize radio-frequency spectrum and satellite orbits, and promote telecom development and digital inclusion.

The term "itu" has other uses, notably as a demonstrative word in Indonesian and Malay. In Indonesian and Malay, itu is a demonstrative determiner meaning "that" or "that one." It is used to refer to something previously mentioned or distant from the speaker (for example, itu rumah saya, "that house is mine"). It is a common part of everyday language and is distinct from sini ("this") and sana ("there" or "over there"). The word appears widely in written and spoken Indonesian and Malay, and can occur in idiomatic phrases and expressions.
