1. 3 Main components of a typical command
Cocoa - Carbon - BSD (CLI) - X11 - Java (Cocoa is native - Carbon is based on OS 9 but still provides OS X performance - X11 is a unix windowing environment)
command - options - arguments
The status indicator lights - Green - yellow - red.
Review network preferences - review network utility preferences - and attempt to connect to different network services

2. How do kerberos and keychain system differ for managing authentication services?
Parental controls
1.) Try another account 2.) Reset the account password 3.) Verify directory service connectivity 4) Verify kerberos authentication & config 5.) Check directory service log files
Single partition drives are easier to setup initially - but aren't as flexible for admin/maintenance. Multiple can segregate data
Kerberos can only be used to authenticate against kerberized services and is often managed on a network-wide scale.

3. How does the firmware password help secure against password changes?
iSync allows you to sync personal info between Mac OS X apps and peripherals like Palm PDAs - and Bluetooth enabled cell phones.
Prevents users from using the reset password utility on the os x install dvd because they cannot boot from it.
Clear-text - encrypted - Kerberos
User preferences are in ~/Library and the format is often Property List - which is just a special XML file.

4. How do permissions in the Finder appear different than those in the terminal?
Interface is any channel through which networks data can flow. Hardware network interfaces are defined by physical network connections - while virtual network connections are logical network connections on top of hardware connections. Protocol is a s
cat - less
So they can navigate to the public or sites folder
Finder shows only 4 different permissions options: read/write - read-only - write-only - and no access. Terminal can show you any possible combination.

5. Different between absolute and relative path
IP addresses identify the location of a specific network device. Subnet masks are used by network devices to identify their local network range. IPv4 addresses are a 32-bit number represented in 4 groups of four octets separated by periods. 0-255.
Any Mac OS X Extended volume including volumes from disk images stored on an AFP share on OS X Server.
They're used to combine complex items into individual folders. Packages appear as a single item.
Absolute always start at the root of the filesystem - whereas relative paths start where the user is current at

6. How does network service order affect network connectivity?
Internet traffic goes through the primary interface.
Defines the directions to a specific item in the filesystem
It enacts itself any time an App crashes or hangs indefinitely. It send an error report and any comments to Apple.
The firmware initializes the Mac's hardware and and locates the booter file on the system volume. The Power-On Self Test (POST) checks for basic hardware functionality.

7. What are resource forks and why have they fallen out of favor?

8. What is the difference between launch daemons - startup items - launch agents - and login items?

Users' public folders
Too many to list. Hehe.

10. What are some common file flags and extended attributes used by Mac OS X?
/System/Library/LaunchDaemons - /Library/LaunchDaemons - /Library/StartupItems - /etc/rc.local (maybe)
It allows Windows XP SP2+ - Vista - and 7 to run natively on the Mac by running a separate partition.
cat - less
Common flags include locked and hidden - Common extended attributes include an items color - spotlight comments - etc.

11. What role does system launchd play in the system start-up?
System launchd is responsible for starting every single system process. It manages system initialization and launches loginwindow.
Code signed items include a digital signature that the system can use to verify the authenticity and integrity of the application or process and its resources.
So they can navigate to the public or sites folder
It records what file operations are in progress at any given moment. If a power failure or system crash occurs - it can verify the integrity by replaying the journal.

12. What are five common directory services and authentication services troubleshooting techniques?
Hold down T on boot - allows the mac to be turned into a very large - and expensive - external hard drive or disc drive.
The firmware initializes the Mac's hardware and and locates the booter file on the system volume. The Power-On Self Test (POST) checks for basic hardware functionality.
1.) Try another account 2.) Reset the account password 3.) Verify directory service connectivity 4) Verify kerberos authentication & config 5.) Check directory service log files

Print and Fax or Sharing Preferences. For windows users - you must enable users' password in the SMB file sharing settings in Sharing Preferences.
This will not change the keychain. They can either unlock the keychain with the old password to sync them - or create a new keychain.

16. What differentiates RAID 0 from RAID 1?
loginwindow displays the login window and then sets up and manages the GUI user environment.
May cause data corruption
They're stored at the root of every volume in a /.Spotlight-V100 folder. A fileVault user's database is stored in his vault in his home user. Mail is in ~/Library/Mail/Mail Envelope. Spotlight plugins can be in any library folder in a folder called S
RAID 0 uses striping to increase performance. RAID 1 uses disk mirroring.

User preferences are in ~/Library and the format is often Property List - which is just a special XML file.
PostScript Printer Description (PPD) files are printer driver files that instruct the CUPS system on how to communicate with specific printer models.

18. What are the two primary automation technologies for the GUI?
Parental controls
Automator is a workflow based application whereas AppleScript is an english-like scripting language
The user's loginwindow process does the following: Request that all user applications quit - quits any user backgroun processes - runs any logout scripts - records the logout to the man system.log - resets device permissions and preferences to defaul
They're used to combine complex items into individual folders. Packages appear as a single item.
