My Mom is in telecommunications. Technology such as radio, telephone, fiber optics, etc.
What does she do?
Specifically fiber-optic communication! They transmit information from one place to another by sending pulses of light through an optical fiber.
Is that basically the internet?
Optical fiber is used by telecommunications companies! So yes, internet but also telephone signals and cable television signals!
That's cool! What else can you tell me?
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.
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
Fiber-optic communication
Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic carrier wave that is modulated to carry information. Fiber is preferred over electrical cabling when high bandwidth, long distance, or immunity to electromagnetic interference are required.
Optical fiber is used by many telecommunications companies to transmit telephone signals, Internet communication, and cable television signals. Researchers at Bell Labs have reached internet speeds of over 100 petabit×kilometer per
