i am buying another computer and naturally i would like to set up internet on it , i thought about buying a switch and use that to share my cable modem between the 2 computers,will that work okay? i never used a switch before so wanna make sure
(btw my isp allows upto 3 ip's so i know for a fact there wouldnt be an issue there) , i know i could get a router however its more expensive and honestly i dont need the extra features,please help

If you actually get three public IP addresses, then a switch will allow you to share the Internet. Note that if they're really public IP addresses, it's very likely that you will NOT be able to share files/printers between the machine. I know that when Comcast issues multiple public IP addresses, they're routinely not in the same subnet, so there will be no communication between the machines.

Truthfully, since a router is only about $20-30 if you do any shopping, there is no reason on this planet that anyone that can afford to have three computers can't afford the extra $10 or so to get a router and solve the problem the right way, rather than the switch.
