The Information Technology or IT is
revolutionizing the way, in which we live and work. It is changing
all aspects of our life and lifestyle. The digital revolution has
given mankind the ability to treat information with mathematical
precision, to transmit it at very high accuracy and to manipulate
it at will. These capabilities are brining into being a whole
world within and around the physical world. The amount of
calculational power that is available to mankind is increasing at
an exponential rate. Computers and communications are becoming
integral parts of our lives.
A few decades back communications used to be
between people-one person to another. But now inanimate objects
are getting into the act-books can tell the cash registers how
much they cost, identity cards can tell the door lock whether to
open or not, automated guided vehicles can tell the host computer
where they are in the shop floor and what they are carrying and
when they will be free, missiles can compare the landscape with
their own map and hit the target with pin-point precision, on the
Internet people engage in lively chats and discussions, play games
even if they are physically in different continents.
The changes mentioned above in computation and
communication adds up to what is called the information revolution
or IT revolution. To survive in this information world one must
keep pace with these changes. This book is written to serve as an
introduction to Information Technology. The book deals with the
fundamental concepts, technologies and theories as well as
advanced concepts and practical applications. The book starts with
an introduction to computers and telecommunications and then later
deals with the latest developments and technologies. This book
also includes sections that will enable a person to perform basic
tasks like using a word processor, an electronic spreadsheet or a
presentation package.
