Supernova remnants are among the most valuable astrophysical laboratory to study numerous physical processes involved in their evolution and interaction with the surrounding interstellar medium. These objects are one of the most important sources of injection of mechanic energy and chemical enrichment of the interstellar medium. They accelerate cosmic rays, generate strong shock waves in such conditions that cannot be reproduced in a terrestrial laboratory. The remnants can emit radiation from radio to gamma ray bands. In this report I describe the relevant radiation processes in the different spectral regimes and the information obtained by multifrequency observations of supernova remnants, including some recent results.
