Importance of Information Technology: The developments in information technology have now paved way for the new axiom 'New scales, new worlds'. Relations between data need, provision and handling have risen as a reflection of technological development. Nevertheless, the technology and the techniques are within certain limits, in operational terms. Particularly, there is still a limit to the quantum of data that can be handled. The value of information technology depends upon the following is beginning to dawn in our midst:
1. Nature and type of sensing of information.
2. Its spatial and temporal resolution.
3. Our capability for processing data into information, storing and handling them in terms of computer facility.
4. The analytical capability with us and the corresponding interpretative capability amongst us.
5. Classifying the conclusions and solutions from the information obtained by us and bringing them into use in a beneficial manner.
The five above, there is no doubt, will give us a clarity of what we know of the world.
It is always a question in the area of communication as to how to deliver the news and ideas that arise from these to a majority. In today's world, there are several communication equipments in daily use. It is also true that some of them are still beyond the reach of a majority of people in this country because of their prices. For example, it is humanly impossible to make available the newspapers to every citizen of India. Similarly, radios and televisions cannot be made available to all of them, either. But there is no doubt that the impact of these media is widespread, throughout the world. According to one source, radios provide vital information to 90 per cent of the Indian population. Television acts in a way useful to 70 per cent of the Indians. They play a vital role in entertainment. Telephones have started functioning in remote villages, besides the towns and cities. But in the western countries, the telecommunications have already become the basic needs. The day is not far off for it to happen in India, as well. Let us now turn to learning the developments that have come about in the fields of telecommunication and its technologies.
Communication Revolution: The world is under the grip of a 'communication revolution' is seen in many ways. This revolution is considered as the 'third wave' of global revolution. The "first wave" of revolution is the 'green revolution' while the 'second wave' of revolution is that of the 'industrial revolution'. The two revolutions (agricultural, industrial) have made a revolutionary change in the development of humankind. It is expected that the third revolution of communication would bring about changes in the world that would surpass all changes that occurred in the earlier revolutions. It has made possible the belief that it is 'One World'. It would also integrate people of all world, in all directions, is talked about throughout.
As the first impact of the appropriate activities of the information technology, the world has begun to shrink. It has now become possible to send the information contained in ten books in a few seconds to a distant place: broadcasting has given way to narrow-casting.
How has this been possible? Let us now look at the historical developments in information and telecommunications, as they are useful to us. Never before in human history has knowledge been so enormous. Also, we have never possessed such communication abilities as we do now. We may consider these information and telecommunications technologies as the problem-solving strategies and facilities. It is even possible to integrate the wealthy North countries with the poverty-stricken South countries in the good cause of amenity expansion, catalysing development, increasing literacy, alleviation of poverty through altruism, nature restoration, world management, promoting peace and humanising the world through these technologies.
Language and New Technologies: In human history, the languages were split and developed as the populations spread and multiplied. Some cultures have gifted their cultures and languages to the outsiders and brought to themselves laurels. Language has alone become the vehicle of communication. Some of these languages have now become the languages of law, administration and the official use through speech, writing and printing.
