Explained in no particular order:
|Self explanatory, this is where your Mac’s applications are kept
|The Developer directory appears only if you have installed Apple’s Developer Tools, and no surprise, contains developer related tools, documentation, and files.
|Shared libraries, files necessary for the operating system to function properly, including settings, preferences, and other necessities (note: you also have a Libraries folder in your home directory, which holds files specific to that user).
|largely self explanatory, network related devices, servers, libraries, etc
|System related files, libraries, preferences, critical for the proper function of Mac OS X
|All user accounts on the machine and their accompanying unique files, settings, etc. Much like /home in Linux
|Mounted devices and volumes, either virtual or real, such as hard disks, CD’s, DVD’s, DMG mounts, etc
|Root directory, present on virtually all UNIX based file systems. Parent directory of all other files
|Essential common binaries, holds files and programs needed to boot the operating system and run properly
|Machine local system configuration, holds administrative, configuration, and other system files
|Device files, all files that represent peripheral devices including keyboards, mice, trackpads, etc
|Second major hierarchy, includes subdirectories that contain information, configuration files, and other essentials used by the operating system
|Essential system binaries, contains utilities for system administration
|Temporary files, caches, etc
|Variable data, contains files whose contents change as the operating system runs
