What does ATM stand for?

• A. Automated Teller Machine
• B. Automatic Teller Machine
• C. Automated Token Machine
• D. Automatic Transfer Machine

Answer: (A)

The main idea here is understanding what the acronym ATM represents as a device used in banking. It stands for Automated Teller Machine. Each part points to its function: Automated means the machine operates on its own without a human teller, Teller refers to the bank staff who would handle similar tasks, and Machine identifies it as a physical device. This combination describes a device that lets customers perform banking transactions automatically, such as cash withdrawals and balance inquiries.

The other options miss the established wording. Automatic Teller Machine is a close form but the widely accepted version uses Automated. Automated Token Machine would imply a device related to tokens, not typical banking transactions. Automatic Transfer Machine would suggest transfers are the machine’s sole purpose, which isn’t how the device is commonly described.
