Visual Studio 2013 and Team Foundation Server 2013 Update 4

I recently had to update my installations of Visual Studio 2013 and Team Foundation Server to Update 4 and I found it surprisingly difficult to get the right search results on the 1st or 2nd hit by searching on Google.  In addition, it is not readily apparent whether the TFS 2013 Update 4 installation package is different from the Visual Studio 2013 Update 4.

For your reference, I am including the direct links to Visual Studio 2013 Update 4 and Team Foundation Server 2013 Update 4 respectively:
