Introduction
Nowadays the use of information technology (IT) constitutes an inseparable part of a
great deal of our daily activities. Information, and generally the technology providing
it, has become a vital strategic and economic asset of companies and organizations and,
moreover, of their executives. The rapid development of information technology as
regards computing systems and software packages, and, simultaneously, the
installation of expanded telecommunication networks, has significantly improved
the management of information, and particularly its disposition and diffusion.
Consequently, information technology, the science of gathering, storage, transmission,
and processing of information, gradually becomes a science of communication.
