Telecommunications technology includes anything used by humans to communicate information over a distance. The concept has been around since the early days of human history, when smoke signals and drums were used to inform a person or groups of people of an event or situation. However, major breakthroughs since the late 1800s have brought the field of telecommunications into the modern age. As early as the telegraph, long distances could be traversed with information. More recent developments include the telephone, radio, television, fax machine and computer, each with its own unique properties to benefit the information exchange of mankind.
