Answer 1

The correct answer is:

(b) Data flow

In the context of software-defined radio (SDR) and cognitive radio, data flow is typically considered an isochronous stream. This means that the data flow is time-sensitive and must be processed at consistent, predictable intervals. Isochronous streams are essential for maintaining the quality of service, especially in applications like voice or video transmission where timing and synchronization are crucial.
