Hello, I am curious to know more about telecomunication from you
You mean the transmission of signals signs, messages, words writings images and sounds? Sure! I am a teacher at a community college in my area, I'd love to help
Who discovered telecommuncation?
I know that some examples of pre-modern long distant type of messages are coded drum-beats and lung-blown horns or loud whistles, so it's not just text messages like everyone thinks. It has been a thing for a while
what year  did man start making use of telecomunication?
I am glad you aren't one of my students! I bet you are a great learner though, I honestly don't know the answer to this. Considering the many varies ways it is done I am sure it dates back to the beginning of time, with smoke signals and signal flags
oh ok, what else can you tell me about telecommunications
That's a better question lol, I am sorry, I am only a substitute teacher, I should of mentioned that in my bragging. But when we do social media we are dong ths over physical media, like cables or on electromagnetic  radiation  My favorite fact on it. Technology is so great. 
Thanks for all your help in taking me from zero educated to 100 :P
I mislead you on one thing, checking my text book I wanted to clarify. It's not telecommunication with the smoke signals and signal flags, it was our early ways of communicating before technology.
