The results on the unpolarized structure functions from DIS experiments and on large pt jet production processes in gamma-gamma and gamma-p collisions are discussed for both real and virtual photons. A few related topics like the QED structure functions of the photon and the structure function of the electron are also shortly discussed.104 pages, 107 figuresHigh Energy Physics - Phenomenologytext
