Difference between Docker registry and repository

Question

I\'m confused as to the difference between docker registries and repositories. It seems like the Docker documentation uses the two words interchangeably. Also, repositories

Answer 1

Docker Hub and other third party repository hosting services are called “registries”. A registry stores a collection of repositories.

As a registry can have many repositories and a repository can have many different versions of the same image which are individually versioned with tags.
