what is the difference between worker process,application pool and application domain? [closed]

Question

can anyone please explain what is the difference between worker process,application pool and application domain? or application domain and application pool are same?

Answer 1

An application pool seperates web applications on a server so it behaves completely independent of the other web applications so if another web application fails, this one wont because its seperate. The worker process basically processes all the requests for a web application. I think usually one application pool uses one worker process by default but it can use more. In process explorer it will show as W3wp.exe. As for the difference between application domain and application pool, I'm not 100% sure but it's already been answered on this forum here:
