<p>Both are derivatives of Unix.</p>
<h2>Kernel vs Full OS</h2>
<p>Linux is just a kernel. the BSDs are both a kernel and an operating system. E.g. FreeBSD provides both the FreeBSD kernel and the FreeBSD operating system. It’s maintained as a single project. If you want to install Linux, you need to choose a Linux distro.</p>
<h2>License</h2>
<ul>
  <li><strong>Linux: GPL License</strong>. It forces them to release the code.</li>
  <li><strong>BSD: BSD License</strong>. You’re free to do whatever you like with the BSD code. If you modify the BSD kernel or distribution and distribute it, you’re not obligated to release the source code.
    <ul>
      <li><strong>Darwin</strong>: the low-level kernel and other software is open-source BSD code, most of the rest of the operating system is closed-source Mac OS code.</li>
    </ul>
  </li>
</ul>
<h2>Both are Unix descendants</h2>
