Firmware - booter - kernel - and system launchd. Primary user environment stages are loginwindow - user launchd - and user environment.
Press the eject button - file>>eject - drag to trash - press eject in the sidebar
System launchd is responsible for starting every single system process. It manages system initialization and launches loginwindow.

7. What are the primary differences between local - network - and mobile accounts?
Review network preferences - review network utility preferences - and attempt to connect to different network services
Local accounts are just for that Mac - network accounts are available anywhere on the network - and Mobile accounts create a cached local copy of a network account for offline access.
If the DHCP request goes unanswered - it'll get a self-assigned IP in the 169.254 range.
Devices providing network services broadcast their existence and Mac OS X picks up on these broadcasts and provides a list of services.
