We present some results on computing Hochs child cohomology groups. We describe the lower cohomology groups and provide several examples. In the particular case of hereditary algebras, radical square zero algebras and inci dence algebras, we construct convenient projective resolutions that allow us to compute their cohomology groups. Finally, we show an inductive method to compute the Hochschild co homology groups.
