What is the purpose of DAMA channel use?

Explanation:
Demand Assigned Multiple Access means channels are allocated on demand to users who need to transmit, matching each request to the available satellite capacity. A control system handles requests and assigns a channel for a specific time when capacity exists, so only active transmissions occupy a channel. This maximizes efficiency by avoiding fixed, unused bandwidth. That’s why this option is the best: it describes allocating resources based on actual demand rather than leaving channels idle or sharing them indiscriminately. The other ideas describe different concepts—equalizing usage, encryption, or broad broadcasting—which aren’t how DAMA operates.
