An analysis of the existing data on photoproduction and electroproduction of protons is made. Koba-Nielsen-Olesen (KNO) scaling is observed in both cases. The scaling function of the nondiffractive ..gamma..p processes turns out to be the same as that for nondiffractive hadron-hadron collisions, but the scaling function for deep-inelastic e/sup -/p collisions is very much different from that for e/sup -/e/sup +/ annihilation processes. Taken together with the observed difference in KNO scaling functions in e/sup -/e/sup +/ annihilation and nondiffractive hadron-hadron processes these empirical facts provide further evidence for the conjecture: The KNO scaling function of a given collision process reflects its reaction mechanism. Arguments for this conjecture are given in terms of a semiclassical picture. It is shown that, in the framework of the proposed picture, explicit expressions for the above-mentioned KNO scaling functions can be derived from rather general assumptions.
