But information alone is not enough. Information has to be processed, put to use by logic and reason before it becomes useful knowledge. Information Technology includes and encompasses within itself the whole technological, social and cultural phenomena that promise an excellent future for mankind.
The 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, Information Technology is the in-thing in the 21 century.
The technological progress during the past sixty years has brought about an explosion in knowledge. Today we have super computers imitating the human brain and even beating it in various fields like fast data processing, huge memory storage and quick retrieval capacity.
These super computers can do as much as Terra 10 floating point operations per second FLOPS and have a bit word length.
The personal computer is today a part of many urban homes in the country. The computer is changing its capacity so fast that while in the 70s the IC chips were operated with 18MHz clock, today the clock rate is MHz. In the near future, we would have computers with a clock speed of MHz.
Similarly, the first microprocessor chip intel produced in early seventies had transistors. We hope to have not in very far distant future, million of these transistors sitting on a tiny little chip.
The semiconductor fabrication technology has made a possible for the latest memory devices to have a capacity of one Gigabyte 10 bytes each, which is equivalent to the information stored in newspaper pages.
A single CD can store in itself the entire works of Shakespeare. The most interesting part of the story of staggering progress is that while the number crunching capacity of the computer is going up in geometrical progression, the price or cost involved is falling down in an almost similar proportion.
This wonder machine called computer has revolutionised life in a big way. With its excellent memory, it has become a source of Internet Information Service. A fathomless ocean of information is available today on these computers on any subject, any phenomenon, anytime and anywhere in the world.

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 a matter of seconds only.
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.
The data communication capability is increasing every day with the help of various advancing technologies like the video data compression, digital video and audio, HDTV etc. The global information Infrastructure has established thousands and thousands of servers and multitudes of personal computers in more than countries.
All these computers have been networked in the Internet System. The Internet, you will be surprised to learn, has taken five years to reach the first 50 million users.
This number is increasing every day. The Information Technology today is rightly called the Technology of the Century as it has found its application and use in every walk society of the world. Distances no longer exist and the world appears to have shrunk into a Global Village.Point of Sale Data Collection During your weekly trip to the grocery store, you purchase bread, milk, cold cereal, bananas, and ice cream.
