  This contribution presents properties of the second quantized not only
fermion fields but also boson fields, if the second quantization of both kinds
of fields origins in the description of the internal space of fields with the
''basis vectors'' which are the superposition of odd (when describing fermions)
or even (when describing bosons) products of the Clifford algebra operators
$\gamma^a$'s. The tensor products of the ''basis vectors'' with the basis in
ordinary space forming the creation operators manifest the anticommutativty (of
fermions) or commutativity (of bosons) of the ''basis vectors'', explaining the
second quantization postulates of both kinds of fields. Creation operators of
boson fields have all the properties of the gauge fields of the corresponding
fermion fields, offering a new understanding of the fermion and boson fields.
