In some sense, if you don't go to deeply in the theory, knowing with Z coefficients is everything. This is the content of the universal coefficient theorem. It often occurs that one can compute homology with other coefficients more easily (e.g. with Z/2 coeffients poincare duality works directly for non orientable manifolds).

Web31. Homology has to do with taking the free abelian group on a set, while cohomology has to do with taking the ring of functions on a set. Algebraic geometry is all about treating an arbitrary ring as the ring of functions on something, so it's not surprising that algebraic geometers care a lot about cohomology. – Reid Barton. Web5 jan. 2024 · Homology, similarity, and alignment. Although homology, similarity, and alignment are all relatively well defined notions in biology and computer science, scientists sometimes get confused about their meaning or the relationships between them. The results range from annoyed colleagues to very annoyed colleagues. So let’s sort these things out.
In mathematics, homology is a general way of associating a sequence of algebraic objects, such as abelian groups or modules, with other mathematical objects such as topological spaces. Homology groups were originally defined in algebraic topology. Similar constructions are available in a wide variety of other contexts, such as abstract algebra, groups, Lie algebras, Galois theory, and algebraic geometry.
