Telecommunication In Modern Day World
Telecommunication is the transmission of messages, over significant distances, for the purpose of communication. In earlier times, telecommunications involved the use of visual signals, such as beacons, smoke, semaphore telegraphs, signal flags, and optical heliographs, or audio messages via coded drumbeats, lung-blown horns, or sent by loud whistles, for example. In the modern age of electricity and electronics, telecommunications now also includes the use of electrical devices such as telegraphs, telephones, and teletypes, the use of radio and microwave communications, as well as fiber optics and their associated electronics, plus the use of the orbiting satellites and the Internet.
The first breakthrough into modern electrical telecommunications came with the push to fully develop the telegraph starting in the 1830s. The use of these electrical means of communications exploded into use on all of the continents of the world during the 19th century, and these also connected the continents via cables on the floors of the ocean. The use of the first three popular systems of electrical telecommunications, the telegraph, telephone and teletype, all required the use of conducting metal wires.
A revolution in wireless telecommunications began in the first decade of the 20th century, with Guglielmo Marconi winning the Nobel Prize in Physics in 1909 for his pioneering developments in wireless radio communications. Other highly notable pioneering inventors and developers in the field of electrical and electronic telecommunications include Charles Wheatstoneand Samuel Morse (telegraph), Alexander Graham Bell (telephone), Nikola Tesla, Edwin Armstrong, and Lee de Forest (radio), as well as John Logie Baird and Philo Farnsworth (television).
Telecommunications play an important role in the world economy and the worldwide telecommunication industry's revenue was estimated to be $3.85 trillion in 2008.[1] The service revenue of the global telecommunications industry was estimated to be $1.7 trillion in 2008, and is expected to touch $2.7 trillion by 2013

History
Early telecommunications
During the Middle Ages, chains of beacons were commonly used on hilltops as a means of relaying a signal. Beacon chains suffered the drawback that they could only pass a single bit of information, so the meaning of the message such as "the enemy has been sighted" had to be agreed upon in advance. One notable instance of their use was during the Spanish Armada, when a beacon chain relayed a signal from Plymouth to London that signaled the arrival of the Spanish warships.
In 1792, Claude Chappe, a French engineer, built the first fixed visual telegraphy system (orsemaphore line) between Lille and Paris. However semaphore systems suffered from the need for skilled operators and the expensive towers at intervals of ten to thirty kilometers (six to twentymiles). As a result of competition from the electrical telegraph, the last commercial semaphore line was abandoned in 1880

The telegraph and the telephone
The first commercial electrical telegraph was constructed by Sir Charles Wheatstone and SirWilliam Fothergill Cooke, and its use began on April 9, 1839. Both Wheatstone and Cooke viewed their device as "an improvement to the [already-existing, so-called] electromagnetic telegraph" not as a new device
The businessman Samuel F.B. Morse and the physicist Joseph Henry of the United States developed their own, simpler version of the electrical telegraph, independently. Morse successfully demonstrated this system on September 2, 1837. Morse's most important technical contribution to this telegraph was the rather simple and highly efficient Morse Code, which was an important advance over complicated Wheatstone's telegraph system. The communications efficiency of the Morse Code anticipated that of the Huffman code in digital communications by over 100 years, but Morse had developed his code purely empirically, unlike Huffman, who gave a detailed theoretical explanation of how his method worked.
The first permanent transatlantic telegraph cable was successfully completed on 27 July 1866, allowing transatlantic electrical communication for the first time. An earlier transatlantic cable had operated for a few months in 1859, and among other things, it carried messages of greeting back and forth between President James Buchanan of the United States and Queen Victoria of the United Kingdom.
However, that transatlantic cable failed soon, and the project to lay a replacement line was delayed for five years by the American Civil War. Also, these transatlantic cables would have been completely incapable of carrying telephone calls even had the telephone already been invented. The first transatlantic telephone cable (which incorporated hundreds of electronic amplifiers) was not operational until 1956.
The conventional telephone now in use worldwide was first patented by Alexander Graham Bell in March 1876. That first patent by Bell was the master patent of the telephone, from which all other patents for electric telephone devices and features flowed. Credit for the invention of the electric telephone has been frequently disputed, and new controversies over the issue have arisen from time-to-time. As with other greatinventions such as radio, television, the light bulb, and the digital computer, there were several inventors who did pioneering experimental work on voice transmission over a wire, and then they improved on each other's ideas. However, the key innovators were Alexander Graham Bell and Gardiner Greene Hubbard, who created the first telephone company, the Bell Telephone Company of the United States, which later evolved into American Telephone & Telegraph (AT&T). The first commercial telephone services were set up in 1878 and 1879 on both sides of the Atlantic in the cities of New Haven, Connecticut, and London, England

Radio and television
In 1832, James Lindsay gave a classroom demonstration of wireless telegraphy via conductive water to his students. By 1854, he was able to demonstrate a transmission across the Firth of Tay from Dundee, Scotland, to Woodhaven, a distance of about two miles (3 km), again using water as the transmission medium. In December 1901, Guglielmo Marconi established wireless communication between St. John's, Newfoundland and Poldhu, Cornwall (England), earning him the Nobel Prize in Physics for 1909, one which he shared with Karl Braun. However small-scale radio communication had already been demonstrated in 1893 by Nikola Tesla in a presentation before the National Electric Light Association.
On March 25, 1925, John Logie Baird of England was able to demonstrate the transmission of moving pictures at the Selfridge's department store in London, England. Baird's system relied upon the fast-rotating Nipkow disk, and thus it became known as the mechanical television. It formed the basis of experimental broadcasts done by the British Broadcasting Corporation beginning September 30, 1929. However, for most of the 20th century, television systems were designed around the cathode ray tube, invented by Karl Braun. The first version of such anelectronic television to show promise was produced by Philo Farnsworth of the United States, and it was demonstrated to his family in Idahoon September 7, 1927

Computer networks and the Internet On 11 September 1940, George Stibitz was able to transmit problems using teletype to his Complex Number Calculator in New York and receive the computed results back at Dartmouth College in New Hampshire. This configuration of a centralized computer or mainframe computer with remote "dumb terminals" remained popular throughout the 1950s and into the 60's. However, it was not until the 1960s that researchers started to investigate packet switching — a technology that allows chunks of data to be sent between different computers without first passing through a centralized mainframe. A four-node network emerged on December 5, 1969. This network soon became the arpanet, which by 1981 would consist of 213 nodes.
Arpanet's development centered around the Request for Comment process and on 7 April 1969, RFC 1 was published. This process is important because arpanet would eventually merge with other networks to form the Internet, and many of the communication protocols that the Internet relies upon today were specified through the Request for Comment process. In September 1981, RFC 791 introduced theInternet Protocol version 4 (IPv4) and RFC 793 introduced the Transmission Control Protocol (TCP) — thus creating the TCP/IP protocol that much of the Internet relies upon today.
However, not all important developments were made through the Request for Comment process. Two popular link protocols for local area networks (LANs) also appeared in the 1970s. A patent for the token ring protocol was filed by Olof Soderblom on October 29, 1974, and a paper on the Ethernet protocol was published by Robert Metcalfe and David Boggs in the July 1976 issue of Communications of the ACM. The Ethernet protocol had been inspired by the ALOHAnet protocol which had been developed by electrical engineeringresearchers at the University of Hawaii

Society and telecommunication
Telecommunication has a significant social, cultural. and economic impact on modern society. In 2008, estimates placed the telecommunication industry's revenue at $3.85 trillion (USD) or just under 3.0 percent of the gross world product (official exchange rate). The following sections discuss the impact of telecommunication on society
Economic impact
Microeconomics
On the microeconomic scale, companies have used telecommunications to help build global business empires. This is self-evident in the case of online retailer Amazon.com but, according to academic Edward Lenert, even the conventional retailer Wal-Mart has benefited from better telecommunication infrastructure compared to its competitors. In cities throughout the world, home owners use their telephones to organize many home services ranging from pizza deliveries to electricians. Even relatively-poor communities have been noted to use telecommunication to their advantage. In Bangladesh's Narshingdi district, isolated villagers use cellular phones to speak directly to wholesalers and arrange a better price for their goods. In Côte d'Ivoire, coffee growers share mobile phones to follow hourly variations in coffee prices and sell at the best price

Macroeconomics
On the macroeconomic scale, Lars-Hendrik Röller and Leonard Waverman suggested a causal link between good telecommunication infrastructure and economic growth. Few dispute the existence of a correlation although some argue it is wrong to view the relationship as causal.
Because of the economic benefits of good telecommunication infrastructure, there is increasing worry about the inequitable access to telecommunication services amongst various countries of the world—this is known as the digital divide. A 2003 survey by the International Telecommunication Union (ITU) revealed that roughly one-third of countries have fewer than one mobile subscription for every 20 people and one-third of countries have fewer than one land-line telephone subscription for every 20 people. In terms of Internet access, roughly half of all countries have fewer than one out of 20 people with Internet access. From this information, as well as educational data, the ITU was able to compile an index that measures the overall ability of citizens to access and use information and communication technologies. Using this measure, Sweden, Denmark and Iceland received the highest ranking while the African countries Nigeria, Burkina Faso and Mali received the lowest

Social impact
Telecommunication has played a significant role in social relationships. Nevertheless' devices like the telephone system were originally advertised with an emphasis on the practical dimensions of the device (such as the ability to conduct business or order home services) as opposed to the social dimensions. It was not until the late 1920s and 1930s that the social dimensions of the device became a prominent theme in telephone advertisements. New promotions started appealing to consumers' emotions, stressing the importance of social conversations and staying connected to family and friends.
Since then the role that telecommunications has played in social relations has become increasingly important. In recent years, the popularity of social networking sites has increased dramatically. These sites allow users to communicate with each other as well as post photographs, events and profiles for others to see. The profiles can list a person's age, interests, sexuality and relationship status. In this way, these sites can play important role in everything from organising social engagements to courtship

Prior to social networking sites, technologies like SMS and the telephone also had a significant impact on social interactions. In 2000, market research group Ipsos MORI reported that 81% of 15 to 24 year-old SMS users in the United Kingdom had used the service to coordinate social arrangements and 42% to flirt.
Other impacts
In cultural terms, telecommunication has increased the public's ability to access to music and film. With television, people can watch films they have not seen before in their own home without having to travel to the video store or cinema. With radio and the Internet, people can listen to music they have not heard before without having to travel to the music store. Telecommunication has also transformed the way people receive their news. A survey by the non-profit Pew Internet and American Life Project found that when just over 3,000 people living in the United States were asked where they got their news "yesterday", more people said television or radio than newspapers. The results are summarised in the following table (the percentages add up to more than 100% because people were able to specify more than one source)
Telecommunications is a general term for a vast array of technologies that send information over distances. Mobile phones, land lines, satellite phones and voice over Internet protocol (VoIP)are all telephony technologies just one field of telecommunications. Radio, television and networks are a few more examples of telecommunication.
While most people associate telecommunications with modern technologies, the strict definition of the term encompasses primitive and even ancient forms of telecommunication. Among these is the use of smoke signals as a kind of visual telegraph. Puffs of smoke were time-released by smothering a fire with a blanket, then quickly removing and replacing the blanket. Widely used by the American Indians, smoke signals could communicate short messages over long distances, assuming a clear line of sight

Other forms of early telecommunications include relay fires orbeacons. Used foremostly in warfare, relay fires required a handful of men posted along a range of hilltops, with the last man closest to the area where troop movement was expected. When armies were spotted in the distance, he would light a bonfire. The fire could be seen from a good distance away by the next man in the relay, who would in turn light his own bonfire, and so the fires were lit in succession along the range, creating an effective telecommunications signal that traveled back over several miles in a relatively short period of time. Finally, the last man in the relay would light a beacon to signal his army below that the opponent was en-route.
The arrangement of a ship's flags and semaphores were other forms of telecommunications. A semaphore was a mechanical device atop a tower with paddle-like blades or flags. The device would be set in a specific position to communicate information.
Throughout the 19th century, telecommunications devices became more sophisticated with the advent of electricity, leading to the telegraph, Morse code, and signal lamps. A signal lamp, the optical version of the telegraph, is a powerful lamp with shutters that block the light in long or short durations to translate to the dots and dashes of Morse code. A heliograph is another optical telegraph -- a mirror used to reflect light to mimic a signal lamp.
In the 20th century, telecommunications reached beyond our planet. In June 1969, the world watched and listened as astronauts walked on the moon. Twenty years later, in August 1989, we would see pictures of Neptune arrive back from the Voyager 2spacecraft, riding radio waves that traveled over roughly three billion miles (4.8 billion km) to reach us in a matter of a few hours

Strides in telecommunications have changed the world immeasurably. While pockets of humankind were once isolated from each other, people now have multiple ways to see and hear what is occurring on the other side of the world in real time. Satellite technology, television, the Internet and telephony keep the globe connected in a humming buzz of interactive voices and pictures. In short, telecommunications has come a long way from smoke signals.
Importance of telecommunication
Communication has been one of the most important aspects of the growth of human society and culture. Without it so many things would not get done, people would be divided, and the world would not be how it is. Telecommunications, the transmission of signals over a distance for a purpose of communication, is also very important.
Telecommunications has a long and creative history behind it. One of the first means of telecommunications, and maybe the first one actually, was the use of smoke signals. In classical and ancient times, this was a very effective means of communication in a smaller, more rural world. Other older methods included the use of sound by such things as drums and horns. Flags, lamps and special towers were uses of optical telecommunication. Later development with a more advanced civilization and an industrious society allowed for the creature of telegraphs, radio, television, and eventually the internet.
Telecommunications provides a lot for the world. The commerce that telecommunications creates is a nice little chunk of the gross world product. It provides business, money and market stability in the world. Not only does it create these things as a product of itself, it benefits and enhances the whole world market by creating a tighter community and allowing for quicker reaction time and exchange of information.
There is also the contribution to science to consider. Development in telecommunication provides helpful research and foundation for other technologies. With the development and enhancements of the radio and understanding how radio waves work, flight has become one of the major benefits of telecommunications. Space and sea travel, exploration, and enhanced vehicles have all come from stronger developments in telecommunications. While telecommunications are not the only factor, the ability to send information back and fourth from one location to another has allowed science to develop in places that can't always be monitored directly or visibly

The world is an ever growing one, and would not be possible without telecommunications. As people moved and countries grew, more and more cities developed across the world. With telecommunications, it made it a lot quicker to relay messages from one place to another. Direct contact of a messenger to the receiver was still used and still is used today in some places and certain locations, but being able to send a message across large areas of land without physically traveling that land allows the message to be received quicker. This has helped tremendously with such things as war, weather problems, geographic problems, illness and health, and trade.
The impact that telecommunications have had on the world is evident. It's one of the leading causes of why the world has grown so big and become so helpful and aware of many issues. Telecommunications promotes a better awareness of society and human life. It helps develop solutions and gather support for causes and problems all over the world, making Earth a little closer and a little safer.
Growing Importance of Telecommunication in modern day
A growing importance of telecommunication was discerned since the last three decades of 20th century for its ever-growing impact on productivity. It's an important economic factor that plays a key role in evaluating the economic growth. It has been identified as the foundation for economic prosperity prerequisite for national development as well as an acute indicator of organizational competitiveness. Not only in economic growth but the telecommunication has greater impact on socio-economic and overall development as well.
Post-modern civilization has a tendency to make a confusion making them equal and furthermore confusing the people that they are alike. But the basic difference between these two terms is that growth is related to increase in quantity what we already have, whereas development means both quantitative and qualitative improvement.
Telecommunication is one of the important means for increasing the economic growth and economic development at length. Telecommunication causes companies to use their input resources as much as possible in an effective way. There has been a sharp controversy on whether or not the investment in IT and telecom provide improvements in productivity and business efficiencies.
Investment on IT and telecom sectors may make poor direct contribution to overall performance of companies until they are combined with complementary investments in business activities, company restructuring, and human capital. As we get various research works from Cobb-Douglas model (was used to examine the impact of Information Technology investment on productivity at Telecommunication Company of Tehran (TCT) and Weighted Least Square (WLS) (was run by SPSS 15 to test hypotheses) - it is explicit that IT investment not only makes the positive contribution to the output of Telecommunication Company but also this contribution is positive after deductions for depreciation and labor expenses.
At the present era there are lots of telecom service providers in the global as well as national market in Australia. They are knowingly or unknowingly all these factors, with a perseverance that telecommunication can accelerate a business as well as a strong brand image have entered into this telecom arena.
Its importance and ever-growing demand was clearly estimated form the fourth edition of the ITU's World Telecommunication Development Report (Malta, March 1998). It showed the growing importance of electronic information for economic, educational and social advancement, highlighting how critical universal access to communications has become. For over 40 million people was waiting for a telephone line worldwide. Where least developed countries have telecommunication penetration levels up to 200 times below that of developed countries
