What term describes a network segment where simultaneous data transmissions collide?

• A. Collision Domain
• B. Confidentiality
• C. Content Switch
• D. Copyright

Answer: (A)

Collision domain describes the network segment where signals on a shared medium can collide if two devices transmit at the same time. In Ethernet networks that use hubs, all connected devices share one collision domain, so simultaneous transmissions can interfere with each other, triggering CSMA/CD to detect the collision and back off before retrying. Switches break up collision domains by giving each port its own separate segment, which prevents collisions from spreading across the network. So, the term that fits is collision domain. The other terms refer to different ideas: confidentiality is about protecting information, a content switch handles traffic based on content, and copyright concerns rights over content.
