What is Pending Intent?

I'm confused about intent and pending intent.
Can anyone explain what exactly is the difference between both? I've searched on SO, I found this link but it didn't meet with my need: https://stackoverflow.com/questions/5633810/what-is-difference-between-an-intent-and-a-pending-intent.

i know Pending intent is an intent which will start later on. Normal intent is started at the time it is passed to startActivity(intent) or StartService(intent).
