5 differences between BSD and Linux

There are many differences between Berkeley Software Distribution (BSD) and Linux.But here, i list 5 differences show as below:

	BSD	LINUX
Licenses	The BSD license does not require that you make sure the next person who uses (or modifies your code) makes that code available.	Linux operating system is licensed under The GPL gives you the right to use the software any way you want, but you MUST ensure the source code is available to the next person who uses it (or your variation of it).
Control	The BSD code is not "controlled" by any one user	Linux kernel is mostly controlled by Linus Torvalds (the creator of Linux),
UNIX-like	the BSDs are much more similar to UNIX because they are, in fact, direct derivatives of traditional UNIX.	Linux, on the other hand, was a newly created OS loosely based on a UNIX derivative (Minix, to be exact).
Kernel vs OS	The BSD project maintains the entire operating system.	The Linux project focuses primarily on the kernel alone.
Upgrades	Upgrade your entire base system to the most recent release by issuing a single command. Or you can download the sources to whatever build you want, unpack them, and build them as you would any application.	upgrade a system by using the built-in package management system. The former updates only the base system; the latter will upgrade the entire installation.
