  The complementarity of the liquid and plasma descriptions of the classical
one-component plasma (OCP) is explored by studying wavevector and frequency
dependent dynamical quantities: the dynamical structure factor (DSF), and the
dynamic local field correction (LFC). Accurate Molecular Dynamics (MD)
simulations are used to validate/test models of the DSF and LFC. Our
simulations, which span the entire fluid regime ($\Gamma = 0.1 - 175$), show
that the DSF is very well represented by a simple and well known memory
function model of generalized hydrodynamics. On the other hand, the LFC, which
we have computed using MD for the first time, is not well described by existing
models.
