The four primary application environments supported by OS X are:
Native OS X applications, which are created using Cocoa or Carbon
UNIX applications, which are primarily accessed via Terminal
Java applications which work as cross-platform applications
X Window System applications which run inside the popular UNIX windowing environment

OS X doesn’t include the Java application or X Window System run time, so they must be downloaded and installed after the OS X initial installation.

Question 3

What are the advantages of application sandboxing?

Answer 3

Sandboxed applications are only allowed access to specific items. They are otherwise completely cut off from the rest of the system and are therefore unable to cause undue harm. All Mac App Store applications are required to be sandboxed.
