What are different IIS isolation levels supported in ASP.NET?

IIS has three level of isolation:-
LOW (IIS process):- In this main IIS process and ASP.NET application run in same process due to which if one crashes, the other is also affected.
Medium (Pooled):- In Medium pooled scenario the IIS and web application run in different process.
High (Isolated):-In high isolated scenario every process is running is there own process. This consumes heavy memory but has highest reliability.
