A few years back I was using written letters as a standard form of communication with all my family members, friends and relatives. But then I came to know about the computers and Internet usage and the endless functions it can perform. From then to now, my letter writing has moved from the paper to the electronic form on the Internet. Have you ever thought about what actually led to the invention of this Internet.
The need for communication was felt way back when the civilization started. Mankind in all ages has evolved its own means of communication.
In the past, communication over distances was based on three ways/kinds:
• Noise (use of drums, echoes)
The pounding of drums in seemingly impenetrable forests was used to alert various tribes from invaders or other dangers. The drums were mainly used by the natives of Africa, New Guinea and tropical
America.
• Optical effect (smoke signals, fire)
Another way was fire signals which were used by the Greeks and Romans usually to signal a military defeat. Fires were lit from mountain to mountain, tower to tower. And, smoke signals were used by Indian tribes and Romans, mostly in battle.
• Physical means (runners, carrier pigeons)
Runners also carried messages from one place to another usually on foot. The first recorded legend of a runner is of Pheidippides - a Greek soldier who ran from the town of Marathon to Athens in 490 BC to announce the Persian’s defeat in the Battle of Marathon. According to sources, he ran the full distance without stopping but moments after delivering his message he dropped dead due to exhaustion.
Homing pigeons carrying messages date back to 6000 years. These pigeons flew up to 40 miles per day. Carrier pigeons were used by the Egyptians and Persians. Genghis Khan established a pigeon relay post across Asia and much of Eastern Europe. Pigeons were used till World War II to carry messages across enemy lines. Till quite recently, the carrier pigeons or men on horseback were the fastest means of communication.
Advent of Newer Technologies
In 1838 telegraph was invented. It was the first modern instrument used in sending messages to a distant place in a short interval of time. Alongside, Samuel Morse introduced his distinctly new language, the Morse code in 1844. The first long distance telegraph message was sent between Baltimore and Washington. The telegraph era ended after World War II.
Taking over from this, the telephone was invented by Graham Bell. This is the first ‘Telecommunication’ mode that drastically revolutionized the lives of ordinary people. The telephone enabled people to speak to each other even when they are physically apart over large distances. The first telephone message was sent in 1876 (from one room to another consisting of seven words!!). By 1890, many cities had primitive telephone systems. It was in 1959 that the first Trans-Atlantic phone cable was installed. The first official Trans-Atlantic message (90 words) took 60 minutes to cross the ocean.
With the arrival of radio and then television, the world shrunk, calling people closer. This also simplified the process of obtaining news and information. Marconi is credited with the invention of radio. He sent and received his first radio signal in Italy in 1895. This was possible by the discovery of electro magnetic waves or radiations prior to 1895. After this came the invention of the television.
The three main stages in radio and television communication include production of messages, their transmission and their detection in a receiver. Messages take the form of electrical signals. These signals are fixed to an electromagnetic wave (often referred to as radio-frequency carriers) of suitable high frequency which carry the messages. In case of radio, the range of the carrier frequency is 300 KHz to 30MHz. For television, the frequency range of the carrier waves is 30MHz to 300MHz.
Discovery of Internet
The current scenario of communication between people has led to various and very big developments in all media spheres. These differences can definitely be noticed in the Telecommunications industry also.
The term ‘Telecommunication’ is referred to, as the communication over large distances by cable, telegraph, telephone, radio. Conceptualizing in a precise manner, it can be explained as the “transmission of signals over vast distances for the purpose of communication”.
The field of telecommunication further progressed by the introduction of computers. A computer is defined as a fast acting device, which can accept large amount of input data, store it in its memory and produce the result in the form of an output. However, it was the Internet, which brought about a big revolution in the field of telecommunications, shrinking borders and effectively changing the world into a global village.
The Internet is a global communication network connected by fiber optic cabling that transmits data by packet switching via the standard Internet Protocol. The origin of the Internet lies in the creation of APRANET (Advanced Research Projects Agency Network), which was a project of the U.S Department of Defense in 1968.
Facing the rapid technology changes, APRANET underwent various modifications till two decades and later it ceased to exist and the Internet came into being. By the mid-90s the World Wide Web became the biggest society trend and since then nothing has remained the same.
By the end of the 90s, the Internet had one million hosts and computers were nine times faster. The widespread use of Internet has allowed commerce and collaboration and interaction between individuals across man-made boundaries.
Today, we see many great advantages of the Internet:
• E-mail is an essentially free communication tool useful in business and to stay in touch with family and friends.
• Information: help through all search engines as huge amount of data is available on any subject.
• Necessary services: from online banking, booking air tickets, hotel reservations and even job hunting can be done on the Net.
• Buying and selling from the comfort of the home.
• Creation of Blogs: Blogs are referred to as online communities where like-minded people from all over can come together airing views and opinions and forming friendships.
After knowing so much about these developments, telecommunication can now be recognized as a key factor in the development of social, economic, commercial and cultural activities. Being a billion-dollar industry it surely helps in providing services and employment to thousands of people. The growth of science & technology has provided people with a capacity to see, hear and communicate with one and all from any corner of the world, hitherto inaccessible regions have become accessible and within seconds one can obtain any information.
According to me, the future of communication lies in communication in space, between planets and perhaps with life forms in distant galaxies…
