Where does Docker store volumes?

Where does Docker store volumes?

For example, we have a docker file in which the service is declared and in the volume we wrote something like:

mysql:
    image: library/mysql:5.6
    ports:
      - "3306:3306"
    volumes:
      - ./mysql/data:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: pass
      MYSQL_DATABASE: app
      MYSQL_USER: app
      MYSQL_PASSWORD: pass

In this case, everything is clear, our database is located in ./mysql/data. But where will it be if we declare the service like this:

mysql:
    image: library/mysql:5.6
    ports:
      - "3306:3306"
    volumes:
      - mysql:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: pass
      MYSQL_DATABASE: app
      MYSQL_USER: app
      MYSQL_PASSWORD: pass

volumes:
    mysql:
