Exchange server Maintenance scripts

In Exchange server 2010 there are some Maintenance scripts  included with the Install of Exchange server,  located in Scripts folder, but there are others that you can download. I am not sure what 's the role of each of them.

These come with the Install of Exchange server:
StartDagServerMaintenance
StartDagServerMaintenance.strings
StopDagServerMaintenance
StopDagServerMaintenance.strings

 These are downloadable:
 Start-ExchangeServerMaintenanceMode  
Stop-ExchangeServerMaintenanceMode  

Any explanation will be very much appreciated.

Thanks

Mike Pfeiffer has a good article on Exchange Server Maintenance Mode See below link.
Exchange Server Maintenance Mode

The other StartDagServerMaintenance and StopDagServerMaintenance are used to update/patch your DAG member without having them go offline. They move the active copies of the databases on different DAG members while you are doing maintenance.

I have used in the past:
StartDagServerMaintenance
 StopDagServerMaintenance
when I updated DAG members.


But never used :
  StartDagServerMaintenance.strings
  StopDagServerMaintenance.strings
And
 
  Start-ExchangeServerMaintenanceMode  
 Stop-ExchangeServerMaintenanceMode  

 
What do they accomplish differently from the 2 I have used

Answers below...
But never used :
   StartDagServerMaintenance.strings
   StopDagServerMaintenance.strings
 And

These files are .psd1 files. They are Module Manifests files which provide the following detail for modules themselves
 -Describe the contents and attributes of the module
- Define the prerequisites
- Determine how the components are processed

Start-ExchangeServerMaintenanceMode , Stop-ExchangeServerMaintenanceMode  vs StartDagServerMaintenance, StopDagServerMaintenance

So the difference here is the following...
StartDagServerMaintenance: this will put the DAG in a maintenance mode specifically for DAG members
Start-ExchangeServerMaintenanceMode: this can put not only the DAG but the entire server into maintenance mode Transport Service, Call Router etc.

Hence the name of each of the scripts StartDAGServerMaintenance and Start-ExchangeServerMaintenanceMode

They are downloadable for Exchange 2010 because they are not natively part of the Exchange 2010 install. However Exchange 2013 has both of these scripts natively so there is no need to download them if you install Exchange 2013.

Hope this is more clear.

Not clear...

Even the first one will put the entire server into maintenance mode.
