 With changing trends the global market of telecommunication is seen to be expanding rapidly. The demand for telecommunication-related products and services and the supply of these products and services by various leading service providers have increased dramatically. The increasing dependence on telecommunication in all sectors ranging from public, private, commercial to the domestic nature has increased tremendously. Each one of us has become so dependent on it that it has almost become impossible to lead a normal life in the absence of telecommunication. At the same time, technological advancements in the field of telecommunication are another reason for the growth of this sector. | |||||||||||||||

Early telecommunication
Early forms of telecommunication include smoke signals and drums. Drums were used by natives in Africa, New Guinea and South America whereas smoke signals were used by natives in North America and China. Contrary to what one might think, these systems were often used to do more than merely announce the presence of a camp.
In 1792, Claude Chappe, a French engineer, built the first fixed visual telegraphy (or semaphore) system between Lille and Paris. However semaphore suffered from the need for skilled operators and expensive towers at intervals of ten to thirty kilometres (six to nineteen miles). As a result of competition from the electrical telegraph, the last commercial line was abandoned in 1880.
MODERN OPERATION
The Internet
The Internet is a worldwide network of computers and computer networks that can communicate with each other using the Internet Protocol. Any computer on the Internet has a unique IP address that can be used by other computers to route information to it. Hence, any computer on the Internet can send a message to any other computer using its IP address. These messages carry with them the originating computer's IP address allowing for two-way communication. In this way, the Internet can be seen as an exchange of messages between computers.
CURRENT SITUATION IN TELECOMMUNICATION
Telecommunication is an important part of modern society. In 2006, estimates placed the telecommunication industry's revenue at $1.2 trillion or just under 4% of the gross world product.
Even relatively poor communities have been noted to use telecommunication to their advantage. In Bangladesh's Narshingdi district, isolated villagers use cell phones to speak directly to wholesalers and arrange a better price for their goods. Few dispute the existence of a correlation although some argue it is wrong to view the relationship as causal.
Due to the economic benefits of good telecommunication infrastructure, there is increasing worry about the digital divide. This is because the world's population does not have equal access to telecommunication systems. A 2003 survey by the International Telecommunication Union (ITU) revealed that roughly one-third of countries have less than 1 mobile subscription for every 20 people and one-third of countries have less than 1 fixed line subscription for every 20 people. In terms of Internet access, roughly half of all countries have less than 1 in 20 people with Internet access. From this information, as well as educational data, the ITU was able to compile a Digital Access Index that measures the overall ability of citizens to access and use information and communication technologies.
