>>2536109Electrical signals are converted from an analog to a digital format, expressed in the form of 1's and 0's, on and off.
Those 1's and 0's are then encapsulated in packets of data called bits, which are then organized into larger packets of data called bytes, and so on.
Those bytes are then transmitted across the internet using a combination of Internet Protocol and Transmission Control Protocol, along with (usually) some form of encryption.
It becomes much more complicated from there, but I basically just described the first 4 layers of the OSI model.
Btw, I recommend reading up on the OSI model if you actually want to have a basic, entry-level understanding of how information technology systems work.
