Connect Two Computers Using A Switch
A switch is a special piece of networking equipment that looks like a router, but which is much simpler. A switch can connect two computers (or more), but it can only connect them on the same network. You can’t use a switch to connect two computers to the Internet unless you plug the switch into a router.
These days, switches are primarily used when you need to connect more computers together than you have ports on your router. For example, server rooms at big companies use switches with 96 ports on them to connect up to 95 computers to a router or another switch.
Although switches are dirt cheap, we suggest that you don’t buy one unless you’re sure you need it to connect two computers.
