title: Do not understand where 2048 comes from
body: <p>Where does the <code>2048</code> number comes from in is the problem?</p>
  
  <p>Consider a file system that uses inodes to represent files. Disk blocks are <code>8 KB</code> in size and a pointer to a disk block requires <code>4 bytes</code>. This file system has <code>12 direct disk blocks</code>, as well as single, double, and triple indirect disk blocks. What is the maximum size of a file that can be stored in this file system?</p>
  
  <pre><code>(12 * 8 KB) + (2048 * 8 KB) + (2048 * 2048 * 8 KB) + (2048 * 2048 * 2048 * 8 KB) = 64 terabytes 
  </code></pre>
  
  <p>I was thinking 8KB/4B, but isn't that 2000?  8000/4.</p>
