Alan already answered your network questions.
With respect to "servers accessing and altering data in each other's
database", it doesn't work like that. *Databases*, managed by *servers*,
are accessed by *client applications* (those are the programs you write
yourself). So, in one model (of many possible), you could write a client
service (an application program) that runs on one server, capable of
querying a database on another server (or other databases on multiple
servers), do something with the data in each and update them all, in a
single, 2PC transaction. This is typically what replication services do.

Database server A can't perform any operations on databases on database
server B.
