manager

I want to know how the update manager for linux works. For instance, how does my linux distro check to see if there are any available updates for download and which servers to download these updates? If I am dealing with 3rd party software not apart of the main distro, how do those programs interact with my update manager to notify me that those programs have available updates? Lastly what would be some good literature on the subject?
