Telecommunications literally means communication at a distance. Although we have been doing this for centuries using a wide variety of media, modern telecommunications has come to refer to communication at a distance electronically. Sometimes our voices and data cross the distance on telephone wires, sometimes we use a cable company's coaxial cables, sometimes we use a videocassette, a DVD or a CD, and sometimes radio-frequency waves carry the communication signals across the distance wirelessly, using cell phones, satellites, two-way radios, even radio and television broadcasting. Telecommunications touches virtually all electronic communication and information technologies and industries. This includes local and long distance telephony, computers and computer networks, broadcasting, cable television, satellite transmissions, terrestrial fixed and mobile wireless, the internet, and even consumer electronics.
