Step-by-Step Solution
Solution:
Step 1: Understand task notifications limitations
Task notifications are fast but designed for simple signals or small data (like a single 32-bit value).Step 2: Consider queues for multiple data items
Queues can hold multiple messages and maintain order, suitable for sending multiple integers reliably.Step 3: Choose best practice
Use task notifications for signaling and queues for actual data transfer to balance performance and correctness.Final Answer:
Use task notifications only for signaling and queues for data transfer. -> Option AQuick Check:
Notifications = signals, queues = data [OK]
Quick Trick: Notifications signal; queues transfer multiple data items [OK]
Common Mistakes:
- Trying to encode multiple values in notifications
- Ignoring data integrity with global variables
- Assuming notifications can replace queues for data
