Un Orden Topológico ordena los nodos de un grafo dirigido acíclico de forma que si hay una camino del nodo A al nodo B entonces A aparece antes que B en la ordenación.
<br /><br />
Ej: 
<br />
<img  alt="Grafo acíclico dirigido" title="Grafo acíclico dirigido" src="http://theproc.es/files/1376" />
<br />
El sentido de las flechas indica las dependencias. A depende de B y C, B depende de C, etc, etc.
