We use applicaiton pools for isolation purpose. Every application within an application pool used the same worker process. Each worker process operates as a separate instance of the worker process executable, W3wp.exe, the worker process that services one application pool is separated from the worker process that services another.

In simplest words we use application pools for ISOLATION purpose.

What is Windows Process Activation Service?
The Windows Process Activation Service (WAS) provides process activation, resource management and health management services for message-activated applications. It manages application pool configuration and the creation and lifetime of worker processes for HTTP and other protocols (net.tcp,net.pipe,net.msmq)

How can we check whether IIS is being installed in my system or not?
To verify if IIS is installed or not we need to go to ’Add or Remove Programs’ utility in the Control panel and click on the ’Add/Remove Windows Components’ in the side menu.

There we must locate an item called "Internet Information Services (IIS)". If this is checked, IIS should be installed. So that you can have your IIS installed in your system if it is not installed
