Telecommunication is the transmission of signs, messages, writings and sounds or information of any nature by wire, optical or other electromagnetic systems. Telecommunication occurs when the exchange of information between communication participants includes the use of technology, it is transmitted either electrically over physical media, such as cables, or via electromagnetic radiation. Such transmission paths are divided into communication channels which afford the advantages of multiplexing. Since the Latin term communicatio is considered the social process of information exchange, the term telecommunications is used in its plural form because it involves many different technologies. Early means of communicating over a distance included visual signals, such as beacons, smoke signals, semaphore telegraphs, signal flags, optical heliographs. Other examples of pre-modern long-distance communication included audio messages such as coded drumbeats, lung-blown horns, loud whistles. 20th- and 21st-century technologies for long-distance communication involve electrical and electromagnetic technologies, such as telegraph and teleprinter, radio, microwave transmission, fiber optics, communications satellites.
A revolution in wireless communication began in the first decade of the 20th century with the pioneering developments in radio communications by Guglielmo Marconi, who won the Nobel Prize in Physics in 1909, other notable pioneering inventors and developers in the field of electrical and electronic telecommunications. These included Charles Wheatstone and Samuel Morse, Alexander Graham Bell, Edwin Armstrong and Lee de Forest, as well as Vladimir K. Zworykin, John Logie Baird and Philo Farnsworth; the word telecommunication is a compound of the Greek prefix tele, meaning distant, far off, or afar, the Latin communicare, meaning to share. Its modern use is adapted from the French, because its written use was recorded in 1904 by the French engineer and novelist Édouard Estaunié. Communication was first used as an English word in the late 14th century, it comes from Old French comunicacion, from Latin communicationem, noun of action from past participle stem of communicare "to share, divide out.
Homing pigeons have been used throughout history by different cultures. Pigeon post had Persian roots, was used by the Romans to aid their military. Frontinus said; the Greeks conveyed the names of the victors at the Olympic Games to various cities using homing pigeons. In the early 19th century, the Dutch government used the system in Sumatra, and in 1849, Paul Julius Reuter started a pigeon service to fly stock prices between Aachen and Brussels, a service that operated for a year until the gap in the telegraph link was closed. In the Middle Ages, chains of beacons were 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. In 1792, Claude Chappe, a French engineer, built the first fixed visual telegraphy system between Lille and Paris.
However semaphore suffered from the need for skilled operators and expensive towers at intervals of ten to thirty kilometres. As a result of competition from the electrical telegraph, the last commercial line was abandoned in 1880. On 25 July 1837 the first commercial electrical telegraph was demonstrated by English inventor Sir William Fothergill Cooke, English scientist Sir Charles Wheatstone. Both inventors viewed their device as "an improvement to the electromagnetic telegraph" not as a new device. Samuel Morse independently developed a version of the electrical telegraph that he unsuccessfully demonstrated on 2 September 1837, his code was an important advance over Wheatstone's signaling method. The first transatlantic telegraph cable was completed on 27 July 1866, allowing transatlantic telecommunication for the first time; the conventional telephone was invented independently by Alexander Bell and Elisha Gray in 1876. Antonio Meucci invented the first device that allowed the electrical transmission of voice over a line in 1849.
However Meucci's device was of little practical value because it relied upon the electrophonic effect and thus required users to place the receiver in their mouth to "hear" what was being said. The first commercial telephone services were set-up in 1878 and 1879 on both sides of the Atlantic in the cities of New Haven and London. Starting in 1894, Italian inventor Guglielmo Marconi began developing a wireless communication using the newly discovered phenomenon of radio waves, showing by 1901 that they could be transmitted across the Atlantic Ocean; this was the start of wireless telegraphy by radio. Voice and music had little early success. World War I accelerated the development of radio for military communications. After the war, commercial radio AM broadcasting began in the 1920s and became an important mass medium for entertainment and news. World War II again accelerated development of radio for the wartime purposes of aircraft and land communication, radio navigation and radar. Development of stereo FM broadcasting of radio
Bahrain the Kingdom of Bahrain, is an island country in the Persian Gulf. The sovereign state comprises a small archipelago centered around Bahrain Island, situated between the Qatar peninsula and the north eastern coast of Saudi Arabia, to which it is connected by the 25-kilometre King Fahd Causeway. Bahrain's population is 1,234,571, including 666,172 non-nationals, it is 765.3 square kilometres in size, making it the third-smallest nation in Asia after the Maldives and Singapore. Bahrain is the site of the ancient Dilmun civilisation, it has been famed since antiquity for its pearl fisheries, which were considered the best in the world into the 19th century. Bahrain was one of the earliest areas to convert to Islam, in 628 CE. Following a period of Arab rule, Bahrain was occupied by the Portuguese in 1521, who in turn were expelled in 1602 by Shah Abbas I of the Safavid dynasty under the Persian Empire. In 1783, the Bani Utbah clan captured Bahrain from Nasr Al-Madhkur and it has since been ruled by the Al Khalifa royal family, with Ahmed al Fateh as Bahrain's first hakim.
In the late 1800s, following successive treaties with the British, Bahrain became a protectorate of the United Kingdom. In 1971, Bahrain declared independence. An emirate, the Arab constitutional monarchy of Bahrain was declared a kingdom in 2002. In 2011, the country experienced protests inspired by the regional Arab Spring. Bahrain's ruling al-Khalifa royal family has been accused and criticized for human rights abuses, including imprisonment and execution of dissidents, political opposition figures and its Shia Muslim population. Bahrain had the first post-oil economy in the Persian Gulf. Since the late 20th century, Bahrain has invested in the tourism sectors. Many large financial institutions have a presence in the country's capital, it is recognised by the World Bank as a high-income economy. Bahrain is a member of the United Nations, Non-Aligned Movement, Arab League, Organisation of Islamic Cooperation and the Gulf Cooperation Council. Bahrayn is the dual form of Arabic bahr, so al-Bahrayn means "the two seas".
However, the name has been lexicalised as a feminine proper noun and does not follow the grammatical rules for duals. Endings are added to the word with no changes, as in the name of the national anthem Bahraynunā or the demonym Bahraynī; the mediaeval grammarian al-Jawahari commented on this saying that the more formally correct term Bahrī would have been misunderstood and so was unused. It remains disputed which "two seas" the name Bahrayn refers to; the term appears five times in the Quran, but does not refer to the modern island—originally known to the Arabs as Awal—but, rather, to all of Eastern Arabia. Today, Bahrain's "two seas" are taken to be the bay east and west of the island, the seas north and south of the island, or the salt and fresh water present above and below the ground. In addition to wells, there are areas of the sea north of Bahrain where fresh water bubbles up in the middle of the salt water as noted by visitors since antiquity. An alternate theory with regard to Bahrain's toponymy is offered by the al-Ahsa region, which suggests that the two seas were the Great Green Ocean and a peaceful lake on the Arabian mainland.
Until the late Middle Ages, "Bahrain" referred to the region of Eastern Arabia that included Southern Iraq, Kuwait, Al-Hasa and Bahrain. The region stretched from Basra in Iraq to the Strait of Hormuz in Oman; this was Iqlīm al-Bahrayn's "Bahrayn Province". The exact date at which the term "Bahrain" began to refer to the Awal archipelago is unknown; the entire coastal strip of Eastern Arabia was known as "Bahrain" for a millennium. The island and kingdom were commonly spelled Bahrein into the 1950s. Bahrain was home to Dilmun, an important Bronze Age trade centre linking Mesopotamia and the Indus Valley. Bahrain was ruled by the Assyrians and Babylonians. From the sixth to third century BCE, Bahrain was part of the Achaemenid Empire. By about 250 BCE, Parthia brought the Persian Gulf under its control and extended its influence as far as Oman; the Parthians established garrisons along the southern coast of the Persian Gulf to control trade routes. During the classical era, Bahrain was referred to by the ancient Greeks as Tylos, the centre of pearl trading, when the Greek admiral Nearchus serving under Alexander the Great landed on Bahrain.
Nearchus is believed to have been the first of Alexander's commanders to visit the island, he found a verdant land, part of a wide trading network. The use of these is not confined to India, but extends to Arabia." The Greek historian Theophrastus states that much of Bahrain was covered by these cotton trees and that Bahrain was famous for exporting walking canes engraved with emblems that were customarily carried in Babylon. Alexander had planned to settle Greek colonists on Bahrain, although it is not clear that this happened on the scale he envisaged, Bahrain became much part of the Hellenised world: the language of the upper classes was Greek, while Zeus was worshipped in the form of the Arabian sun-god Shams. Bahrain became the site of
