Contacts, calendars, notes, and bookmarks are synced from (or to) your computer, so if you add, change, or delete them on the device, they are changed on your computer, and vice versa. You can also sync contacts with your Yahoo! or Google Address Book.

Email-account settings, music, movies, TV shows, podcasts, and photos are synced one-way, from your computer to your device (though you can import photos taken with iPhone to your computer and you can transfer purchases from your device to iTunes). Well, you also can transfer songs from ipod to mac with a great software tool. Using an iPad, you can send photos back to your computer (typically captured on iPad via the Camera Connection Kit).

If you like, you can set your device to sync with only a portion of what's on your computer. For example, you might want to sync only a group of contacts from your address book, or you may want to sync only songs from certain playlists so you don't fill your device with your music.
