A dummy activity is used in AOA (Activity on Arrow) diagrams to represent dependencies not otherwise possible to show.  They are zero time activities added just to connect dependent tasks.

Computer programs use AOA since it is easier to represent and manage.  In general, the AON is now the predominant method.

There is a nice explanation of AOA and AON diagrams at: http://onlinemba.uww.edu/media/mcs785/modules/mod4b/part2.pdf
