Application pools allow you to isolate your applications from one another, even if they are running on the same server. This way, if there is an error in one app, it won't take down other applications.

Additionally, applications pools allow you to separate different apps which require different levels of security.

Here's a good resource: <a href="http://www.developer.com/net/asp/article.php/2245511/IIS-and-ASPNET-The-Application-Pool.htm" rel="noreferrer">IIS and ASP.NET: The Application Pool</a>

An application pool is a group of urls served by worker processors or set of worker processors. 

There can exist any number of application pools. 

In IIS it is possible to create more than one application pool.

An application in different application pool runs in different worker processors.

Advantage: If an error occurred in one application pool will not effect the applications running in another application pool.

Application pools are used to separate sets of IIS worker processes that share the same configuration and application boundaries.

Application pools used to isolate our web application for better security, reliability, and availability and performance and keep running without impacting each other . The worker process serves as the process boundary that separates each application pool so that when one worker process or application is having an issue or recycles, other applications or worker processes are not affected. One Application Pool can have multiple worker process Also.

Or we can simply say that, An application pool is a group of one or more URLs that are served by a worker process or set of worker processes. Any Web directory or virtual directory can be assigned to an application pool. So that one website cannot be affected by other, if u used separated application pool.

The application Pools element contains configuration settings for all application pools running on your IIS. An application pool defines a group of one or more worker processes, configured with common settings that serve requests to one or more applications that are assigned to that application pool.

Because application pools allow a set of Web applications to share one or more similarly configured worker processes, they provide a convenient way to isolate a set of Web applications from other Web applications on the server computer.

Process boundaries separate each worker process; therefore, application problems in one application pool do not affect Web sites or applications in other application pools. Application pools significantly increase both the reliability and manageability of your Web infrastructure.

IIS-Internet information Service is a web server used to host one or more web application .
Lets take any example here say Microsoft is maintaining web server and we are running our website abc.com (news content based)on this IIS.
Since, Microsoft is a big shot company it might take or also ready to host another website say xyz.com(ecommerce based).

Now web server is hosting i.e providing memory to run both websites on its single web server.Thus , here application pools come into picture .
abc.com has its own rules, business logic , data etc and same applies to xyz.com.

IIS provides two application pools (path) to run two websites in their own world (data) smoothly in a single webserver without affecting each ones matter (security, scalability).This is application pool in IIS.

So you can have any number of application pool depending upon on servers capacity

An application pool is like a pond, if I create 2 application pools, first application pool has 100 fishes and another application pool has 200 fishes, here fish is like an application in application pool.
They are managed by worker processes. Best advantage is: if pound number-1 has bad water and cases all fish are effected then there is security of fish in pound number-2. Like this if any application pool is effected by any problem but there is not any effect of this problem in application pool 2 so security in improve, and another profit is that is you provide all necessary authentication and rights to all applications in a single application pool.
