Nowadays, we can define
Information technology as the fundamental change which is taking place in the
nature and application of technology in business. This change has far-reaching
implications for an organization. Another way, Information Technology is a
developing technology that aims at obtaining the maximum information with
minimum of resources, labour or time.
Its also the study or use of
electronic equipment especially computers, for storing, analysing and distribution
of information of all kinds, including words, numbers and pictures. IT is driven by the demands of the
new, competitive business environment on the one hand and profound changes in
the nature of computers in the other. Information Technology systems come in
the shape of many technologically advanced devices which help deliver important
information to managers and thus they
use this information to make crucial decision regarding the operations of their
organization. It includes and encompasses within itself the whole
technological, social and cultural phenomena that promise an excellent future
for mankind. 21st century is a century
of Information Technology. Just as steam
engine emerged to be the technology of the 19th century and computer technology
enhanced the capacity of human brain in the 20th century, such as now
Information Technology is the in-thing in the 21 century.
We can’t think of the days when
transfer of information was confined to oral transmission or written message
only. Today, any amount of information
can be conveyed from any corner of the world to any other farthest corner, in
few seconds. We have satellite
communication, optical fibre communication, terrestrial microwave communication,
coaxial cable communication and several other advances systems that enable us
to transport enormous amounts of data at the huge rate of several gigabytes per
second to the farthest points in the world by the implementation of information
technology. The data communication
capability is increasing every day with the help of various advancing
technologies which include video data compression, digital video and audio,
HDTV etc.
The Information
Technology today is rightly called the Technology of the Century as it has
found its application in every corner of
the world. Information Technology, as
expected, has brought about a sea change in the functioning of our world. It has proved to be a great boon to
industrial productivity also. Internet
makes all the information available regarding product design, product quality,
latest technologies, market survey,
financial conditions likewise all the development in every corner of the world. For more
