What does TTY stand for?

• A. Teletype
• B. Teletypewriter
• C. Teletype System
• D. Teletype Device

Answer: (A)

TTY stands for Teletypewriter—the device that converts between typed text and telecommunication signals for transmission over a line. Historically, teletypewriters were the actual machines used to send and print text over telephone networks, so the acronym TTY is tied to that specific hardware and its text-based communication role. That association makes it the best answer because it names the exact equipment and concept behind the term, rather than a broader or more generic idea like just a teletype, a system, or a device. In later contexts, you’ll also see TTY as a shorthand in computing for text terminals, which still reflects the original idea of text-based input/output.
