Travel Cable

[MrRX7]

how does data / signals / power travel through cables?

MAGIC! no seriously for power though scientifically it is a stream of electrons through a conductive material (metal) the electrons the grab onto other atoms (things that need power) and the charge of these atoms is always positive needing the electrons to balance them so they can be neutral creating energy. Hope this was helpful bit late here in Straya

I think that electricity moves in cables.

@DrunkAssassin ok and for signal / data ?

[Guest GRRigger]

for optical fibre cable is light

also, in future electronics it will be light also, because of graphene allowing it

 

photons that is

@ thanks how about normal cables we have today like mouses, keyboards, monitors, internet etc and are they all the same?

those excluding optical fibre for internet use electricity as previously mentioned. the concept is the same, singnal is composed of 1 and 0 states -> on and off states respectively. That doesnt mean 0 state is absolutelly no electrical current, its just a little.

copper wires are for internet also.

 

but hold on right there. you are learning things from middle out. i suggest you pick cuple cuputer science books, from architecture , computing to programming  etc

 

first learn basic expressions, names and basics in computer architecture and then pursue forward

internet is good source of knowledge too, but i suggest books as a primary source of reliable info. use internet just to google a thing or two that you dont understand, its often simplified in yotube videos so its understandable for wider audience.

 

learning things on forum is no-go because we are very unreliable source and often times not very good teachers
