Application of Stack & Queue in Embedded Systems

Which data structure is used for handling function calls in microcontrollers?

• Queue

• Linked List

• Stack

• Array

In an embedded system, what is the role of a queue in real-time task scheduling?

• Storing return addresses

• Managing recursive function calls

• Ensuring tasks are executed in FIFO order

• Saving CPU state during interrupts

Why is a stack used in an automobile airbag system?

• To store execution state during airbag deployment

• To buffer incoming sensor data

• To schedule multiple sensor readings

• To handle long-term data storage

Which of the following is a real-world example where a queue is used in an embedded system?

• Interrupt handling in microcontrollers

• Recursion in robotics pathfinding

• Sensor data buffering in IoT weather monitoring

• Function call execution in ESP32

What is the key difference between stack and queue usage in embedded systems?

• Stack follows FIFO, while Queue follows LIFO

• Stack follows LIFO, while Queue follows FIFO

• Both follow LIFO

• Both follow FIFO
