Ok...this is one very basic thing Im confused on. with regarding to hubs/routers/and switches
I know hubs all contain one large collision domain (which is "bad" but can someone explain why) and a switch contains a collision domain for each port.
But what exactly is a broadcast domain, and what is it in relation to hubs/switches/routers (which gives out how many and what)
and What is the purpose of a collision domain.....and why exactly is having everyone connected to one collision domain bad.
Im sorry if this is very basic, but the book im reading didn't really go into them as deeply as I wished. (So I do apologize for the basic question) and googling brought up WAYYY too many results. Plus I trust you guys more :)
I apologize if this belongs elsewhere, but im not aware of a "networking" stack exchange.
