  The mass-generation mechanism is the most urgent problem of the modern
particle physics. The discovery and study of the Higgs boson with the Large
Hadron Collider at CERN are the highest priority steps to solve the problem. In
this paper, the Standard Model Higgs mechanism of the elementary particle mass
generation is reviewed with pedagogical details. The discussion of the Higgs
quadric self-coupling \lambda parameter and the bounds to the Higgs boson mass
are presented. In particular, the unitarity, triviality, and stability
constraints on the Higgs boson mass are discussed. The generation of the finite
value for the \lambda parameter due to quantum corrections via effective
potential is illustrated. Some simple predictions for the top quark and the
Higgs boson masses are given when both the top Yukawa coupling and the Higgs
self-coupling \lambda are equal to 1.
