SCCM 2007 has three basic types of distribution points i.e Standard, Server Share and Branch Distribution Points. Each role had benefits, but there was not always one type that met all the administrator requirements.
This concept is now changed in SCCM 2012 and had come with one Role which is standard distribution point which merges Standard, Branch and Server Share distribution points.
This Distribution Point now has a new storage format called the Content Library. The Content Library replaces SMSPKG shares as the default folder structure to host content. The Content Library now stores all content on the distribution point in a single instance storage, this means each unique file is only stored once on the distribution point, regardless of how many times it is referenced by a package. It also stores the file once on the distribution point even if it is contained in multiple packages!
