The first breakthrough into modern electrical telecommunications came with the telegraph in 1830's. The use of all these electrical means of communications became blasted into use on all the continents of the world during the 19th century.

A revolution in wireless communications began in the first decade of the 20th century with 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 communications include Samuel Morse(Telegraph), Alexander Graham Bell (Telephone) , Edwin Armstrong (Radio),as well as John Baird (Television).

Telecommunications play an important role in the world economy; the worldwide telecommunications industry's revenue was estimated to be $3.85 trillion in 2008.

A communication network is a collection of transmitters, receivers and communication channels that send messages to one another. Examples of this include the atmosphere for sound communication, glass optical fibers , cables for communications by way of the voltages and electric current in them, and free space for communications using visible lights, infra-red waves, ultra-violet light and radio waves. A channel is termed as a physical medium that carries a signal between the transmitter and the receiver. Radio waves travel through a perfect vacuum just as easily as they travel through air, fog or clouds.

With the invention of computers, communication has become easier and faster. Laptops, note books, iPad are the latest versions of computers and Internet. Used computers and refurbished computers also can play an important role in social media communications. Cheap computers work exactly in the same way as the new ones.

Telecommunications has a significant social, cultural and economic impact in modern society. On the micro-economic side, companies have used telecommunications to help build global business empires. This is self-evident in the case of online retailer Amazon.com. Other chain of companies has also been benefitted from better telecommunication infrastructure. In cities throughout the world, home-owners use their telephones to organize many home services ranging from pizza deliveries to electricians. In Bangladesh, isolated villagers use cellular phones to speak directly to wholesalers and arrange a better price for their goods. Even relatively poor communities have been noted to use telecommunication to their advantage. http://www.electrocomputerwarehouse.com
