easy📝 Conceptual Q1 of 15

FreeRTOS - Task Notifications

AThey use message buffers that add overhead

BThey require dynamic memory allocation for each notification

CThey rely on kernel objects that increase context switch time

DThey use a single 32-bit variable within the task's control block

Step-by-Step Solution

Solution:

Step 1: Understand task notifications storage
Task notifications are stored as a 32-bit value inside the task control block, avoiding extra kernel objects.
Step 2: Compare with other IPC methods
Queues and semaphores require separate kernel objects and more memory management, increasing overhead.
Final Answer:
They use a single 32-bit variable within the task's control block -> Option D
Quick Check:
Single variable storage reduces resource use [OK]

Quick Trick: Task notifications use a 32-bit variable inside the task [OK]
