What does TDD stand for?

• A. Telecommunications Device for the Deaf
• B. Telecommunications Device for Deaf People
• C. Teletype Device for the Deaf
• D. Telecommunication Device for the Deaf

Answer: (A)

TDD stands for Telecommunications Device for the Deaf. This name reflects devices that let deaf or hard-of-hearing people use the telephone by typing text that is transmitted over the phone line and shown to the recipient. It’s the traditional expansion of the acronym, with the plural “Telecommunications” used in official terminology. The other options mix up either the wording or the type of device (for example, Teletype devices or singular “Telecommunication” phrasing), which isn’t the standard name for TDD.
