[In brief..]

ucs.exe is essentially the chat/mail server.

shared_memory.exe creates (pre-loads) binary memory-mapped files for certain information in the database. (This should only be run when the server is down and after any
changes to db values. Most people add this to their startup.bat file.)

loginserver.exe is the initial access point for clients. World servers also log into this and clients are passed off when a server is selected.

world.exe is essentially the 'world' controller and is where character selection/creation occurs.

eqlaunch.exe is a launch controller for zone.exe and may or may not be present in your configuration..based on whether you used the 'traditional' server install method or used
the newer perl install script.

zone.exe is where the magic happens. All in-game experience occurs here.


A lot of these 'servers' are connected to each other and some process calls are directed around, as needed.
