1. What is the difference between safe boot - safe mode - and safe login?
Authentication is who am I?Authorization is what can I do?
Describe containers in the file system
Safe boot refers to when the system is starting up - safe mode is when the system is actually running - and safe login is when the system starts up the user session.

It stores the home folder as an encrypted sparse-bundle disk image
Info pane in Network Utility
It will allow any user to search any attached non-system volume if ownership is ignored.

Devices providing network services broadcast their existence and Mac OS X picks up on these broadcasts and provides a list of services.
Terminal - Single User Mode - >Console from login window - SSH
System Profiler - Disk Utility - Reset Password Utility - Firmware Password - Restore from Time Machine Backup - Startup Disk - Terminal - Network Utility

cat - less
User accounts - user groups - computer accounts - computer groups - network file mounts - management settings - and collaboration information.
The client uses the subnet mask to decide if the client is on the LAN. If it's not on the LAN - then it sends the data to the IP address of the local router. Traffic continues through routers until it reaches the destination.

5. What happens during user log-out?

6. What are three common troubleshooting techniques for issues involving failure to connect to network services?
Hold down T on boot - allows the mac to be turned into a very large - and expensive - external hard drive or disc drive.
Review network preferences - review network utility preferences - and attempt to connect to different network services
Find the third-party resource causing the problem. Start in verbose mode and see where the startup fails.
AFP - SMB - FTP - NFS - WebDAV
