Communication plays very important role in the human life. Since the moments of our existence we communicate our wants and needs. In the earlier days communication was very difficult due to the lack of proper means of communication. If anybody wanted to convey a message to a person who is living far away, that message used to be sent with the help of human being only. For a longer distance and more detailed message peageon post was used. These all means were very costly, uncertain and time consuming also. Because of all these reasons there was a great need of efficient means of communication to save time and money and hard work.
On March 10, 1876, in Boston, Massachusetts, Alexander Graham Bell invented the telephone. The device was itself; a crude thing made of a wooden stand, a funnel, a cup of acid, and some copper wire.. Since the death of Alexander Graham Bell in 1922, the telecommunication industry has undergone an amazing revolution. Bell’s “electrical speech machine” paved the way for the Information Superhighway. World is celebrating 46th “ World Telecom Day” on 17th May,2011.This year the theme of Telecom Day is ‘ Better Life in Rural Community with ICT’
Use of various means of telecommunication now becomes an integrated part of society. Information found to be one of the most important elements for the efficient growth of an economy. With efficient use of telecommunication one can remove various constraints of all the sectors in the economy resulting into increased productivity and better administration. Effective controlling mechanism can be possible only through better communication and with better use of telecommunication equipments. In the developing countries earlier telecommunication was a big problem because all the means of communications were confined to the rich people only. But with the revolution in this sector now all the means are also available to middle and lower class people who play vital role in the growth of economy of any country.
As we know that balanced growth of all sectors is very important for any country to become super power in the world. The development in any one sector is not enough for that. Optimum and efficient use of telecommunication in every sector is most important if any country wants to become superpower or at least self dependent. Hence it is necessary to see the importance of telecommunication in the various sectors in the economy.
Infrastructure is the basic physical and organizational structures needed for the operation of a society or enterprise or the services and facilities necessary for an economy to function The term typically refers to the technical structures that support a society, such as roads, water supply, electrical grids, telecommunications, and so forth. Viewed functionally, infrastructure facilitates the production of goods and services; for example, roads enable the transport of raw materials to a factory, and also for the distribution of finished products to markets and basic social services such as schools and hospitals. In military parlance, the term refers to the buildings and permanent installations necessary for the support, redeployment, and operation of military forces.
As we already know that transport infrastructure is extremely important from economic development of any country which includes roads, bridges, and tunnels and for safe traffic various telecommunication equipments are very important. For the smooth traffic in the entire transportation sector i.e. road, rail and air and water use of telecommunication devices is increasing day by day.
This is the most important sector in the Indian economy as our country is mostly depending on the agriculture for its economic development. Few years ago farmers were in a bad condition because of lack of proper information regarding the weather, regarding the price of their commodity, regarding the proper advice from the agro expert, regarding the market condition etc. Middlemen were exploiting the farmers as farmers were not able to communicate with their counterpart in different parts of the country and abroad to know about the prices of their crops. But now due to the revolution in the telecommunication sector the farmers even from rural areas they can take the advantage of the various telecom devices. Now farmers can discuss their problems with the expert and can take their advice regarding farming by using different types of telecommunication devices.
The literacy rate in India is 70.04% as per the latest census. Though it is improving fast but still it is behind the world literacy rate i.e. 84%. In the rural area the condition of the education is still poor. But due to the latest technology in the telecommunication sector one can run a school without being physically present there. With the use of internet a professor can give a lecture from distance to the entire classroom and even the students can ask the questions and can clear their doubts. With the use of multimedia students can understand the subject well as they actually see the things happening, they can also appear for various examinations by using online services and can make use internet for their research work.
Distance learning, which provides an educational structure for students not in face-to-face contact with a teacher, is an example of the dramatic changes in learning activity resulting from telestructure and teleprocess. Compared to traditional correspondence learning, teleprocessed distance learning allows many different combinations of audio, video, and data exchange and interaction.
Information and telecommunications technologies play very important role to provide and support health care when distance separates the participants. According to Dr. Hamadoun I Toure “If we are going to be able to deliver health care for all this new century of connectivity, it will be through cooperation and partnership between the technology and healthcare sectors” Telecommunication is receiving increasing attention not only in remote areas where health care access is troublesome but also in urban and suburban locations. Video conference is very important when the doctors are not able to visit the patient place. Doctor can give advice to his counter part with the help of video conferencing when there are some complications in the health of a patient.
Telecommunications can also expand home health care service access through new attachments to home telephone service, providing consultation and monitoring services as needed, especially to the less mobile elderly population, while reducing the number of trips to health centers. Care will be more cost effective when it is based on electronic access. Personal medical records, extensive and current best medical practice information, and consultations delivered by teleconference to the most appropriate location, which might be remote from the health care professional is possible only because of telecommunication.
Government agencies at all levels are introducing new applications of telecommunications for a variety of functions, primarily to improve the quality of service to the public, but also to reduce the cost of providing service and to improve efficiency. Some examples of the use of telecommunications have been in the area of document handling, to make it easier for agencies to process the paperwork associated with issuing regulations, granting permits, recording transfers of property, improving the use of information to collect taxes or assessments, and processing claims for benefits. Many of these applications of telecommunications allow agencies to deliver services to clients in a matter of minutes rather than hours and by telephone rather than in person.
Telecommunication devices can be most useful during natural calamity in any part of the country. At the time of earthquakes, floods and cyclones valuable lives can be saved with the help of telecommunication devices.
Today telecommunication is the lifeblood of business sector. We can not imagine any organization without the use of telecommunication. In every sector of business, telecommunication plays unavoidable role.
Telecommunications, which is essential to today’s smooth business operations, is the transmittal of data and information from one point to another. Telephoning, faxing, e-mail, the World Wide Web – none of these essential business services would be available without fast and reliable telecommunications and so, the concept of electronic commerce, popularly called “e-commerce” would be impossible. Managers can use telecommunication technology for better controlling mechanism and better administration.
Telecommunications technology can reduce geographical distance to an irrelevant factor. E-mail, voice mail, faxing, file transfer, cellular telephony, and teleconferencing allow for full communication, whether among managers, between managers and their staffs, or among different organizations .Telecommunications can also be used by one person to monitor another person’s performance in real time. Telecommunications is used to communicate directions and receive feedback without requiring people to coordinate their schedules to hold a meeting. And the use of e-mail has brought some secondary benefits to business communications, by establishing a permanent written record of, and accountability for, ideas. The result is more accurate business communications. As we know that in the manufacturing firms one department depends on other department because output of one department is input of another department. For example, when the sales department receives a purchase order from a customer, it must communicate the order to the warehouse, which needs the information to prepare the package. The warehouse workers must then forward shipping documents to the accounts receivable department for billing, and so forth. With telecommunications, all documents can be accessed electronically by many different departments at the same time.
We should thank telecommunication, because it makes the world a global village. The distance of people from different countries gets closer. With the application of its technology, keeping in touch with other people becomes uncomplicated. We really live in the world of telecommunication, it makes our life convenient, and we should take advantages of this technology.
