You may be interested in the book "Implementing Discrete Mathematics: Combinatorics and Graph Theory with Mathematica", by Steven Skiena (Addison-Wesley, 1990). The current version of Mathematica, at least, includes the relevant packages of Mathematica functions; these include some dealing with connected components: << DiscreteMath`Combinatorica` [load the add-on package] ? ConnectedComponents [ask for brief information] "ConnectedComponents[g] gives the vertices of graph g partitioned into \ connected components."
