areas where space is wasted in a typical disk filing system
<p>I am doing some revision for a System Architecture exam and came across this question from a past paper(below). I was not sure where to begin with it as it does not specify the type of filing system. The only thing I could think of when it comes to wasting space is the length of which can be variable.</p>

<p>Any help on the best way to tackle the below question, would be greatly appreciated. </p>

<pre><code>Briefly discuss the areas where space is wasted in a typical disk filing
system, and indicate how a system designer may keep this to a
minimum. Note that, in this context, space wastage excludes user
actions, and is concerned principally with overheads within the system
itself.
