Question

The primary advantage of user-level threads over kernel-level threads is _______ .

• A. Lower context-switch overhead
• B. Better parallelism on multicore CPUs
• C. No need for synchronization
• D. Higher priority scheduling

Hint:

User-level threads are more efficient in terms of context-switching, which is one of their key advantages over kernel-level threads.

Answer 1

The Correct Option is A

User-level threads have a lower context-switch overhead compared to kernel-level threads because context switching between user-level threads does not require kernel intervention. This makes user-level threads faster in terms of switching between them. The other options do not represent primary advantages of user-level threads.
