WANT TO KNOW HOW TO NETWORK 40 COMPUTER'S WITH TWO SWITH AND A ROUTER. AM A NEWBIE.
You're pretty brave taking this on but as the previous poster says, it's as easy as that - physically. To advise further, posters will need to know which software the 40 boxes are using and whether you're going to use one of them as a server. Linux is better - in my opinion - at handling the server role but it all depends on what the 40 machiens are actually going to do.
