Question: What is adUseClient and adUseServer?
Where it is going to affect in runtime?

Answer: These are constants in CursorLocationEnum of CursorLocation property on a ADO Connection object.

If the CursorLocation property is set to adUseClient then the recordset will be in read only mode, i.e. the recordset cannot be used to update records in the database. A recordset with the CursorLocation asUseClient is typically used when an active Recordset is Disconnected for viewing data.

By setting the CursorLocation as adUseServer the recordset can perform any transaction with the database.

The previous answer is wrong..

These are constants in CursorLocationEnum of CursorLocation property on a ADO Connection object.

If the CursorLocation property is set to adUseClient then the recordset will be available at client as disconnected recordset, where user can do any changes on it, then using the 'ActiveConnection', we can connect to the database once again and update the modifications.

By setting the CursorLocation as adUseServer the recordset is available at server side with active connection, can perform any transaction with the database.
