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?
Well, early means of communication were signal flags, beacons, telegraphs, snd heliographs! Telecommunications haven't been around forever!
That's interesting I can't imagine a world without instant communication!
