WHAT is family sharing?
Apple ID is the username for Apple services. It is either shares its name with a pre-existing email address, or uses a dedicated iCloud.com address.
iCloud acct., iTunes acct. are just sub-accounts that can be easily accessed using the same Apple ID!
It seems that many people are under the impression that you need more than one account, possibly one for each Apple service, which simply is not true.
4 Services that use the Apple ID:
1. App Store – used to purchase Apps and Games for iOS, macOS, etc.
2. iTunes Store – used to purchase music, movies, ringtones, etc.
3. Apple Music – service for streaming up to something like 40 million songs
4. iCloud – used to sync data such as pictures, contacts, notes, calendar events, etc. across multiple devices and to backup non-synced iOS data
Family Sharing allows a family organizer to connect individuals with different Apple IDs who want to share purchased content, but still wish to keep their private data separate, preventing cross-contamination of data. Among other things, parents can use family sharing to manage Apple IDs for minors under the age of 13.
