DISN stands for?

• A. Defense Information Systems Network
• B. Defense Internal Systems Network
• C. Digital Information System Network
• D. Defense Information and Security Network

Answer: (A)

Defense Information Systems Network is the official DoD-wide, secure communications backbone that carries voice, video, and data across all branches and installations, managed by DISA. This name reflects the broad, interconnected information systems infrastructure the Department of Defense relies on for interoperable operations. The other options don’t fit because they either alter the organization’s scope (internal or digital-only meanings), misuse singular/plural forms, or add words not used in the official designation.
