  Cataclysmic Variables (CVs) are a distinct class of X-ray binaries
transferring mass from a donor star to a compact star accretor, a white dwarf.
They constitute a laboratory for accretion physics, mechanisms and disk theory
together with dynamics of outflows and interaction with surrounding medium. Our
understanding of the X-ray emission from CVs has shown substantial improvement
in the last decade with the instruments on board present X-ray telescopes. We
have a better understanding of the boundary layers and the accretion shocks
using high sensitivity instruments and/or grating X-ray spectroscopy attaining
high spectral resolution yielding temperature and velocity diagnostics. In
addition, high time resolution utilizes accretion mode diagnostics with
characterization of the variability of the gas flow in discs. Here, I briefly
review the X-ray properties of CVs with a highlight on Intermediate Polars,
Dwarf Novae and Classical/Recurrent Novae.
