Telecommunications
Telecommunication is the transmission of signs, signals, messages, words, writings, images and sounds or information of any nature by wire, radio, optical or 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 communication is considered the social process of information exchange, the term telecommunications is often 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, and optical heliographs. Other examples of pre-modern long-distance communication included audio messages such as coded drumbeats, lung-blown horns, and loud whistles. 20th and 21st century technologies for long-distance communication usually involve electrical and electromagnetic technologies, such as telegraph, telephone, and teleprinter, networks, radio, microwave transmission, fiber optics, and 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, and other notable pioneering inventors and developers in the field of electrical and electronic telecommunications. These included Charles Wheatstone and Samuel Morse (inventors of the telegraph), Alexander Graham Bell (inventor of the telephone), Edwin Armstrong and Lee de Forest (inventors of radio), as well as Vladimir K. Zworykin, John Logie Baird and Philo Farnsworth (some of the inventors of television).
Technology
The technology industry has grown dynamically over recent years as businesses and consumers buy more software, computers and mobile devices. Additionally, a side effect of web-based solutions and mobile devices has been an explosion of sensitive, private data requiring complex security software products.
The near-term is expected to center on software increasingly entering day-to-day activities as well as the rise of big data predictive analytics and artificial intelligence. Phones and mobile computing devices are providing new platforms on which software publishers can compete. Additionally, the rapid move toward cloud computing is opening an array of software possibilities as phones and tablets are no longer limited by low storage capacity. Finally, demand for security software to protect data is expected to rise considerably as new technologies continue to enter everyday life more and more.
