RTOS and Memory Management Quiz

What is the primary goal of a scheduler in an RTOS?

• Maximize throughput

• Ensure predictability in task execution

• Minimize power consumption

• Manage file systems

Which of the following is an example of a predictable system response in RTOS?

• A task runs after an unspecified delay

• A task completes before the next task's deadline

• Tasks are executed in random order

• Tasks are executed based on available resources

What is a key feature of memory management in RTOS?

• Virtual memory management

• Memory allocation at runtime

• Predictable memory access time

• Memory defragmentation

Which memory segment is used for storing program instructions?

• Stack

• Heap

• Text Segment

• BSS Segment

What is the purpose of the BSS (Block Started by Symbol) segment?

• Stores program instructions

• Stores initialized global variables

• Stores uninitialized global variables

• Allocates dynamic memory

Which of the following is an example of dynamic memory allocation?

• Declaring an array of fixed size

• Allocating memory using `malloc()` function

• Initializing global variables

• Declaring static variables

What is the key difference between the heap and stack in memory management?

• The stack is for dynamic memory allocation, and the heap is for function calls

• The heap grows upwards, while the stack grows downwards

• The stack is for long-term storage, and the heap is for short-term storage

• The stack is used for global variables, and the heap is used for local variables

Which memory segment stores dynamically allocated memory in an RTOS?

• Stack

• Heap

• Text Segment

• Initialized Data Segment

Which of the following tasks is managed by the RTOS kernel's memory management?

• File handling

• Task scheduling

• Memory allocation and deallocation

• Network packet routing

Which of the following ensures tasks in an RTOS meet their deadlines?

• Random scheduling

• Dynamic memory allocation

• Predictable task scheduling

• Memory fragmentation
