What are two differences among user-level threads and kernel-level threads? Under what circumstances is one type better than the other?

(1) User-level threads are unknown by the kernel, while the kernel is aware of kernel threads. 

(2) User threads are listed by the thread library and the kernel schedules kernel threads. 

(3) Kernel threads require not be associated with a process while every user thread belongs to a process.
