hehe ur CTO uses HUbs, lol mine uses switches frm SMC and whoa the speeds r gr8 on Lan, actually i didnt think that someone wuld invest that much in gettin switches rather than hubs, but to my supriese he uses a 100mb/s one.and as to ur question yes Hubs r used to connect computers togeather where there is need to connect more than 2 comps.
