Telecommunication
Telecommunication is the transmission of signs, signals, messages, words, writings, images and sounds or information of any nature by wire, radio, 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 often 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 often used in its plural form because it involves many different technologies.
German Radio Intelligence Operations during World War II
German Radio Intelligence Operation during World War II were signals intelligence operations that were undertaken by German Axis forces in Europe during World War II. In keeping with German signals practice since 1942, the term "communication intelligence" () had been used when intercept units were assigned to observe both enemy "radio and wire" communication. When the observation of only enemy "radio" communication was undertaken, the term "radio intelligence" (). The term "intercept service" () was also used up until 1942. Towards the end of World War II, about 12,000 troopers of the German Army were engaged in intercepting the radio traffic of an increasingly powerful adversary.
Invention of radio
Many people were involved in the invention of radio as we know it today. Experimental work on the connection between electricity and magnetism began around 1820 with the work of Hans Christian Ørsted, and continued with the work of André-Marie Ampère, Joseph Henry, and Michael Faraday. These investigations culminated in a theory of electromagnetism developed by James Clerk Maxwell, which predicted the existence of electromagnetic waves. Maxwell published "A Treatise on Electricity and Magnetism" in 1873, stimulating many people to experiment with wireless communication. Others experimented without the benefit of his theories.
Telecommunications engineering
Telecommunications engineering, or telecoms engineering, is an engineering discipline centered on electrical and computer engineering which seeks to support and enhance telecommunication systems. The work ranges from basic circuit design to strategic mass developments. A telecommunication engineer is responsible for designing and overseeing the installation of telecommunications equipment and facilities, such as complex electronic switching systems, and other plain old telephone service facilities, optical fiber cabling, IP networks, and microwave transmission systems. Telecommunication engineering also overlaps with broadcast engineering.
Morse code
Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. It is named for Samuel F. B. Morse, an inventor of the telegraph. The International Morse Code encodes the ISO basic Latin alphabet, some extra Latin letters, the Arabic numerals and a small set of punctuation and procedural signals (prosigns) as standardized sequences of short and long signals called "dots" and "dashes", or "dits" and "dahs", as in amateur radio practice. Because many non-English natural languages use more than the 26 Roman letters, extensions to the Morse alphabet exist for those languages.
Internet censorship and surveillance by country
This list of Internet censorship and surveillance by country provides information on the types and levels of Internet censorship and surveillance that is occurring in countries around the world. Detailed country by country information on Internet censorship and surveillance is provided in the "Freedom on the Net" reports from Freedom House, by the OpenNet Initiative, by Reporters Without Borders, and in the "Country Reports on Human Rights Practices" from the U.S. State Department Bureau of Democracy, Human Rights, and Labor. The ratings produced by several of these organizations are summarized below as well as in the Censorship by country article.
Telegraphy
Telegraphy (from Greek: τῆλε "têle", "at a distance" and γράφειν "gráphein", "to write") is the long-distance transmission of textual or symbolic (as opposed to verbal or audio) messages without the physical exchange of an object bearing the message. Thus semaphore is a method of telegraphy, whereas pigeon post is not. Telegraphy requires that the method used for encoding the message be known to both sender and receiver. Many methods are designed according to the limits of the signalling medium used. The use of smoke signals, beacons, reflected light signals, and flag semaphore signals are early examples.
