How do you recognize the version of SQL Server you want to install?

There have been many versions of SQL Server released over a long period of time and of course these are followed up by Service Packs (SP). It is hard to know which version is going to be installed.

There is an unofficial chart lists of all the known SP;s, Cumulative Updates(CU), patches and hot-fixes from SQL Server 7.0 to SQL Server 2017.
