How can I figure out what is my tablet's lcd screen density.

Is there any settings option I could check to see the display resolution configurations?
Is there any other way for it?


Question: In which server does the snapshot agent run?
Answer: The Snapshot Agent (snapshot.exe) runs on the Distributor.

From Books Online:

Replication Agents Overview


  Snapshot Agent
  
  The Snapshot Agent is typically used with all types of replication. It
  prepares schema and initial data files of published tables and other
  objects, stores the snapshot files, and records information about
  synchronization in the distribution database. The Snapshot Agent
  runs at the Distributor. For more information, see Replication
  Snapshot Agent.


However, the stored procedure sp_startpublication_snapshot is executed at the Publisher on the publication database and is used to start the Snapshot Agent job that generates the initial snapshot for a publication.

When you configured replication and created the publication, you specified the accounts in which the Snapshot Agent will run under at the Distributor and the Publisher.  This account information is saved.  This is covered in Snapshot Agent Security.

Even though you execute sp_startpublication_snapshot from the Publisher, it already has all of the necessary information to connect to the Distributor and start the Snapshot Agent.
