The ZMan [MVP/Moderator]:
The downloadable redists (and the one included in every SDK) are the offline version of the Web Installer (WI) containing all previous and current versions. But, because it is quite large, it is mostly used to put onto the distribution medium. The WI, on the other hand, will download and install only the missing runtimes, which makes the WI preferred version for online distribution.

The not so known part of the rest: It is
Björn or Bjoern, but never Bjorn.
