**I ended up asking a few questions actually so I don’t expect everyone to sit and answer all but if you happen to know the answer to one I would love to know**
For example internet
Say someone on the other side of the world sent you a message, what would that look like?
*Knowing nothing, I’m going to guess what I think please correct me (I’m just guessing so you can see what I am asking because I don’t know how to ask the question like the question sounded weird but idk how else to say it)*
So my guess, probs 100% wrong
– so person touches phone screen to type and send message
– screen receives some sort of heat signals or something and on each area of the screen it has some sort of information saying what to do when the person touches that spot
– the information goes to the computer in the phone and then relays the information onto the screen
– then when sending a message or whatever, whisky on wifi or phone network the information goes from the phone to the wifi/phone network through electrical currents in the air????? That look like what?? Is it like electrons that connect like a tunnel and it moves from the phone to the router/modem/phone tower???
– then it goes to the satellite?? By the same type of tunnel thing?
– then from satellite to other persons router/phone tower?
– then that information goes to their phone computer
– then the computer sends signal to their screen
That was probably so wrong lmfao please correct me and also tell me what it actually looks like if we were to see the electricity or whatever is happening
Edit: *whilst not whisky lmfao
Edit: also how do computers have lights? Like say a phone. If you turn it off no light, turn it in it has light on the screen. So does the electricity from when you charge it get stored somewhere in the phone then when you turn it on the electricity goes into the tiny squares that make up the screen? Then how does it change colours? And if that’s not correct how does it work?
Also just computers in general. First off who found out how to make a computer. What were they doing to do that like, how did they know how to get electricity (or whoever “found” electricity first) and make a box thing with microchips etc. Wtf is a microchip and how did they make it and put information on it. Just literally the whole thing computers are so complicated and I don’t get how someone could invent that.

well in a phone there are two common screen technologies available. lets pretend electricity is water and voltage is pressure, then start with what produces light here. An LED can be thought of as a sprinkler head on a garden hose if there is no pressure nothing comes out, no light. when you want the sprinkler to spray you turn the valve on the hose partly until the sprinkler has enough pressure to spray, if you want more light you keep turning the valve and the sprinkler will spray more.
OLED displays use a grid of millions of three different tiny LEDs. those three being Red, Green, and Blue (RGB). when it turns on only red you see red, if it turns on red and blue you see magenta since they are so small our eyes kinda blend them together as one dot, blue is blue, blue and green is cyan, green is green, finally green and red make yellow. combinations of these can “make” almost any color we can see. there are loads of websites and free tools where you can play with sliders for each color to better see that in action
LCDs (liquid crystal display) are tough for me to explain so ill come back to it later or someone else might explain those properly.
