Hey Guys/Girls,
I'm back to this site but to this new forum(Tech Board) .My Question is realated to Operating Systems and might be not out of place here.
After reading difference between user-level threads and kernel-level threads ,now I am in doubt of context switching.Context switching is managed by OS when switching between processes/threads but google didn't clarify me when i asked it that in which case more number of switching will take place for these cases :
1). User-level thread switched to another user-level
2). Kernel-level thread switched to another kernel-level
3). User-level thread switched to kernel-level
Anyone having a know-how please make it clear
