Telecommunications refer to the exchange of information with electronic and electrical means at a considerable distance. A complete telecommunication system consists of two or more stations equipped with transmitting and receiving devices. A unique arrangement of transmitters and receivers, called a transceiver, can also be used in many telecommunications stations.
Telecommunication devices include telephones, telegraphs, radios, microwave communication systems, fiber optics, satellites, and the Internet.Telecommunications are also known as telecommunications. Telecommunications is a universal term used for a wide range of information transmission technologies, such as cell phones, land lines, VoIP, and transmission networks.
In telecommunications, data is transmitted in the form of electrical signals known as carrier waves, which are modulated into analog or digital signals for the transmission of information. Analog modulation like that used in broadcasting is amplitude modulation. Digital modulation is just an updated form of this.
Telecommunications and broadcasting are administered worldwide by a United Nations agency called the International Telecommunication Union (ITU). Most countries have their own agencies to enforce telecommunications regulations.
