What is the difference between this "book" and a research paper? I don't know a lot about the scientific research and its concepts. What is the difference between this book and any research paper?

From my understanding of the research world, I know that link.springer is a journal and journals publish research papers after reviewing. If that is the case, then what is that book doing in link.springer? Is it really just a book? or Do people call it "published book"?
Springer publishes books as well as journals. This particular item is a reference book published by Springer. You can certainly cite chapters of a book like this.
