Is USD Coin the same as USD?

Excuse me, I'm a bit confused about something. Could you please clarify for me? Is USD Coin actually the same as the traditional United States Dollar, or USD, that we use in our daily lives? I've heard people talking about it as if it's some sort of digital equivalent, but I'm not quite sure how it differs, if it does. Could you possibly explain the similarities and differences between these two concepts to me? It would be greatly appreciated.
