you buy it from the itunes store then sync it on your ipod
When you sync your iPod Touch to iTunes, your music and your apps are synced into iTunes. Nothing happens to the apps, the best description I can think of for what it is would be a backup for all your files on your iPod. If something happens to your iPod, you can order a new one and sync it, and all of your apps and music from the last time you synced your iPod will be put onto it. That is why you are recommended to sync your iPod often, just in case something happens to it, whether your iPod gets its files deleted, or if it gets broken.
