Show hintHide hint
Think about what happens in a simultaneous access scenario.
Question 2.
Give one benefit of using atomic operations.
Show hintHide hint
What can happen if two threads try to change the same data?
3Question 3.
What is the primary purpose of atomic operations?
- A. To speed up execution
- B. To ensure data consistency
- C. To simplify coding
- D. To parallelize tasks
Show hintHide hint
Why do we care about consistency in multithreading?
4Question 4.
True or False: Atomic operations can cause race conditions.
- True
- False
Show hintHide hint
Recall the definition of atomic operations.
Question 5.
Given two threads incrementing a shared counter, compare and contrast how atomic operations versus traditional locks would handle this scenario. Discuss in terms of performance and data integrity.
Show hintHide hint
Look into how each method deals with simultaneous access.
Question 6.
Create a small piece of multithreaded code that demonstrates a race condition and then rewrite it using atomic operations. Analyze the differences in behavior.
