How Does WiFi Work?
start off with the basics, everything can be eventually boiled down to binary number i.e zero and one (0,1), my voice or my this stupid content and everything.After all yoy may know that a computer's CPU only recognizes two terms "on and off", now the main thing that sets WI-FI apart from the ethernet is the way it transmits data with ethernet data is converted into an electrial signal carreid by a wire. however, with WI-FI, the data is carried by somthing that doesn't require wires. Radio waves, the technology is similiar to the way your car radio picks up a signal but with the wi-fi, there's a two way conversation unfortunately since these radio waves are travelling through the air. They are subject to interference weirdly enough the radiation emitted by your microwave oven can actually affect your wi-fi, so to avoid this as much as possible, WI-FI signals are transmitted at a certain frequency either 2.4Ghz or 4.5Ghz. these waves are sent back and forth between your computer and a wireless router allowing for you to be onneted to the internet and read an article this one. so i want to send a picture to your computer the data will be broken down into small packets and tiny groups and will then be direted to different routers until eventually, it reaches you .the packets are then reassembled to form the image this entire protocol is called TCP/IP and its very similiar to how you send an object to mail. Granted everything is much more cpmlicated than how i'm putting it but the basics aren't too difficult to understand.
