Prevents derivation of classes or overriding of methods.
<pre class="brush:csharp;">
public sealed class Circle : Shape
</pre>
you cannot derive a class from Circle

<pre class="brush:csharp;">
public class Circle : Shape
{
public sealed override void Draw()
{
.....
}
}
</pre>
seal can be applied to only overriden methods.
=== Why ? ===
Sealed classes are slightly faster because of some run time optimizations.
