Q3. What are the three components of CEMA?
Answer: Cyberspace operations, electronic warfare, and spectrum management operations.
Q4. What information technology infrastructures make up the cyberspace domain?
Answer: The internet, telecommunications networks, computer systems, and embedded processors and controllers.
Q5. True or False: Cyberspace is part of the other domains and is not a separate domain.
Answer: False — cyberspace is a distinct domain, though it coexists with and is embedded across the land, air,
maritime, and space domains.

Q13. What is the difference between cyberspace defense and DoDIN operations?
