What are differences between AssemblyVersion, AssemblyFileVersion and AssemblyInformationalVersion?

There are three assembly version attributes. What are differences? Is it ok if I use AssemblyVersion and ignore the rest?

MSDN says:

• AssemblyVersion:

  Specifies the version of the assembly being attributed.

• AssemblyFileVersion:

  Instructs a compiler to use a specific version number for the Win32 file version resource. The Win32 file version is not required to be the same as the assembly's version number.

• AssemblyInformationalVersion:

  Defines additional version information for an assembly manifest.
