What information technology enables rapid transmission of documents?

• A. Fax machine
• B. Email
• C. Telephone
• D. Courier

Answer: (A)

Rapid transmission of documents is achieved by a technology that can send a readable copy directly to another location without delay. A fax machine does this by scanning a paper document, sending the image over telephone lines, and printing an exact copy at the receiving end. This delivers a hard copy quickly and across distances, often faster than mailing or courier services and without needing digital files on both ends. While email also speeds up sending documents, the fax specifically performs direct, near-immediate paper-to-paper transmission, which is why it’s the best fit for rapid document delivery. The other options either rely on physical handoffs (courier) or require different infrastructure (email over the internet) and do not represent the immediate, device-centered transmission process that fax provides.
