Part 4 Data Management Lesson 13- 16 Flashcards
Why does the Finder hide certain folders at the root of the system volume?
Because users don’t need to have access to those items. (If users need access to these UNIX items, they can access them from Terminal.)
Which two methods are used to hide items from the Finder?
1) periods at the beginning of their filenames
2) hidden file flag enabled
What does OS X use bundles or packages for?
To combine complex items into individual folders.
How does an alias differ from a symbolic link?
An alias contains information that allows the system to keep track of the original item if it’s renamed or moved within the same volume whereas the symbolic link is broken if any changes are made to original item
Why would you use an archive file instead of a disk image? Why would you use a disk image instead of an archive file?
Archive files are much simpler to create in the Finder and are compatible with third-party operating systems.
Disk images are more difficult to create and manage but offer greater flexibility (easily modified and converted) but are not compatible with third-party operating systems.
What type of file is created by the Finder when you select the Archive option?
A compressed zip archive file.
Which action on OS X is set as the default for opening zip archive files?
Double-clicking expands the contents of the zip archive
Which OS X application is responsible for the creation and management of disk images?
Disk Utility
What are the 4 default top-level folders visible in the Finder?
1) Applications,
2) Library,
3) System,
4) Users,
What are six common system resources? What purpose does each resource serve?
1) Extensions, which attach themselves to the system kernel
to provide hardware and peripheral driver support
2) Frameworks, which are shared code libraries that provide additional software resources for both applications and system processes
3) Fonts
4) Preference files, which contain application and system
configuration information
5) LaunchAgents and LaunchDaemons, used by launchd to provide services that automatically start when needed at system startup or at user login
6) Logs, which are text files that contain error and progress entries from nearly any application or system service
What are the four system resource domains? What purpose does each domain serve?
1) USER: containing applications and system resources specific to each user account
2) LOCAL: containing applications and system resources available to all users on the local Mac
3) NETWORK: (optional), containing applications and system resources available to any Mac that has an automated network share
4) SYSTEM: containing applications and system resources required to provide basic system functionality
What purpose does the ~/Library/Containers folder serve? What items will you find in this folder? What is the advantage to this file type?
To contain resources for sandboxed applications. The system creates and maintains a separate container folder for each sandboxed application the user opens. A sandboxed application is more secure because it can access only items inside its container.
What happens when a user double-clicks a font file?
automatically opens a preview of the font in the Font Book application. From here, the user can click the Install Font button to copy the font into ~/Library/ Fonts.
How can you identify duplicate fonts?
The Font Book application shows a small dot next to the name of any font that has duplicate resources.
What’s a file system metadata? What are some examples of file system metadata?
Information stored outside of a file or folder. Examples include file flags, extended file attributes, and permissions.
