  This volume contains the proceedings of the 7th International Workshop on
Developments in Computational Models (DCM 2011) which was held on Sunday July
3, 2011, in Zurich, Switzerland, as a satelite workshop of ICALP 2011.
  Recently several new models of computation have emerged, for instance for
bio-computing and quantum-computing, and in addition traditional models of
computation have been adapted to accommodate new demands or capabilities of
computer systems. The aim of DCM is to bring together researchers who are
currently developing new computational models or new features for traditional
computational models, in order to foster their interaction, to provide a forum
for presenting new ideas and work in progress, and to enable newcomers to learn
about current activities in this area.
