Not sure if this is the right place to ask but when i want to go to a website like beehaw.org, my router queries its DNS server which responds with the IP address. But my router doesn’t know where to find that IP so it asks a nearby router if it knows and that router passes that info to another router until they find the path.
If wifi is radio waves and radio waves travel at the speed of light where as down a copper wire data travels at only partial speed of light, why is wifi slower?
Is it simply interference from other signals causing constant retransmissions or what?
Also what is a route? Why can’t i just shoot a packet from my router to the public internet and that website’s router picks it up. Why does it need router’s in the middle?
You need to undo what your teachers in school taught you a bit and remember that there is air as well as interference. When data is sent from one place to another you need signal integrity and it is a lot easier to ensure signal integrity over a cable than through air. The reason to your second question is quite simple does your router have a cable to all other routers in the world? Answer no. So you need to pass allot of different routers on your way to the websites router. An easy way to remember is the other name for the internet aka the World Wide Web, Web like a spider! I would recommend reading on Wikipedia more about this stuff it’s quite interesting!
