Nice paper that compares a large number of different codes (FD, FV, FE). Perhaps not state-of-the-art but still mostly valid.

The simple answer is that we use step functions for the finite difference solution and continuous functions for the finite element solution (the simplest being linear functions). In the end we have the same gross structure of matrix equations and invert the matrix to solve for the dependent variables.
