Methods of communications have changed drastically over the
years. From snail mail to telex, fax, and telephone, and now to
email, SMS and video conferences; and from ship to shore
radio communication, radio telex VSAT communications and
mobile telephony, the march has been wide-ranging and rapid.
The Internet and Information Highway—the World Wide Web,
has been the icing on the cake. The scenario has changed
considerably with the advent of email, file transfer, ERP,
making communication a lot simpler and more cost-effective.
Communication tariff has also had a sea change with STD
calls at 50 paise per minute or less, with the result that there is
much wider use of new communication technologies across
the world.
The communication revolution has had the biggest impact on
human society after the industrial revolution. We can send to
and receive information from any part of the world without
moving from our seat. So much is happening in the world that
we need to keep track of, that a time has come to marshal the
knowledge for the lay user so that various systems of
communications available today are put in their correct
perspective, and the average individual or organization can
make the most effective use of these systems to meet their
communication needs.
The book attempts to give individuals and multi-locational organizations (MLOs) the right
perspective of various communication tools available in the world today so that they may
derive the maximum benefit from these tools to meet their respective needs. It not only
describes the communication needs of people, the optimum communication options
available, but also delves into the uses of telephony, next generation networks, private
networks, special requirements for enterprises, computation of bandwidth, and cloud
computing, among others. The book explains the present methods of protecting your
data through different types of firewalls, their pitfalls, and newer and better ways of doing
this. The book would be useful to practicing professionals in telecom and data-com, and
to IT Infrastructure professionals.
