Communication is an essential element of human existence. The transfer of information characterizes it. The best way to illustrate this is to discuss the evolution of the telephone. This extraordinary invention changed the way businesses are managed and the way people conduct their day to day lives.
Alexander Graham Bell patented the first telephone in 1876. Prior to his receiving the patent, three men were working towards the same goal: Antonio Meucci, Alexander Graham Bell, and Elisha Gray. Both Gray and Bell were working on a telegraph system on which more than one message at a time could be sent over a single wire. Gray, declaring that instruments to convey the human voice were mere playthings, decided he would concentrate on the “more practical” telegraph.
Continuing on in history, the first manually switched commercial telephone exchange opened in 1878. Only 21 subscribers were connected. The first automatic telephone switch was installed in 1892, until this time, operators manned the switches around the clock. In 1915, that first cross-country commercial line was formally opened between New York and San Francisco. For a single voice e

Despite individual skepticism, the delivery of new services will decide the survivability of phone companies in the next digital era. Qwest further forged partnerships with Lucent, Nortel, Netscape, and NBC. As a result, new companies forecast the break-up of the monopolizing long distance telephone corporations of the past. This appears to be the way of the future, and possibly the death of the local exch!
ange carriers. Fiber-optic systems, on the other hand, are transmitting digital data at rates of 3.
It is entertaining to note, the telephone throughout history was not always well received. 10 March, 65-79
Virtural Events: The Wireless Story. The electrical resistance and systems engineering considerations prevent copper from transmitting data at rates higher than 1. In moving information from place to place in quantum leaps of ease and speed, it has greatly accelerated the rate of scientific/technological changes in modern industries. In the early days, voices over the phone were almost inaudible. This invention paved the path for the invention of the first mobile telephone in 1941. The outcome, two years from now, will be a national phone infrastructure with more than 80 times the capacity it had three years ago. Fiber-optic cables, considered the “superhighways” of communication because of their high signal-carrying capacity, are a must for future telecommunications companies.
