POE has many goals and many uses; to give a few of them:

1.Provide a cooperative scheduling and multitasking environment rivalling threads and IPC
2.Simplify the development of protocol-driven network clients and servers
3.Provide an architecture for creating state machines
4.Abstract away a lot of the boring I/O details from complex programs

As you can see, POE is a difficult thing to describe,but the main point is that POE attempts to hide the menial details of event-driven programming.
