The fine structure of the quiet Sun

The observed properties of the small-scale features visible in the quiet photosphere - the granulation, of convective origin, and the network bright points, associated with kG magnetic fields - are described. The known properties of the magnetic flux tubes associated with network bright points are also presented. Empirical models derived from the observations are discussed, as well as a few theoretical models of particular importance for the understanding of the origin of the small-scale features of the quiet photosphere. Finally, the observational evidences showing that the structure of the granulation and of the photosphere network are varying over the solar cycle are reported
