Here is a an analogy you might use for non-programmers: Computer programs are like instruction manuals to tell the computer what to do. In traditional programs, there is one great book containing all the instructions. In OO programming, in the computer’s virtual universe, there is an instruction book attached to every object that tells the computer what it can do with each object and how. All Dalmatians come with two instruction books, a care and feeding of Dalmatatians, and a generic care and feeding of Dogs. The Cocker Spaniels come with a specialised care and feeding of Cocker Spaniels book, and the exact same book on care and feeding of Dogs. The instructions in the specific books can override the general instructions or add to the general instructions in the Dog book.
For a language to be considered officially object-oriented it needs three features:
