Can someone explain me the difference between those three devices?
In: 1512
Hub: That’s a guy with a megaphone. Shouts everything out to everyone. Now imagine a crowd of 500 people and each guy is responsible for 5 people. There is no coordination, you just have to listen and try and figure out what is meant for you.
Switch: That’s the post office. They receive your package, knows where it needs to go and drops it off at your door.
Router: That’s kinda like the train system. They know in which direction your stuff needs to go and takes it there, handing it over to the post office from above.
