There are two ways to run a Network using 10/T. Computer to Computer, or Computer to Hub (the Hub connects to all other computers.) Obviously, a Hub must then be used when 3 or more computers need to be networked. When only 2 computers need to be networked, a special type of cable, called cross-over cable can be used. The only problem with that, is further expansion. When you get a 3rd computer, you have to also buy a hub.

Just like the NICs, the Hub can be a bottleneck in your network speed. If you have 100/TX cards, and a 10/T hub, your WHOLE network (not just a segment as with NICs) will run at 10Mbps. If you get 100/TX cards, it’s suggested to get a 100/TX hub to go along with it, unless you plan on upgrading in the future due to money constraints.

The number of ports (places you plug the cable in) is also important. Usually, you’ll want to make room for further expansion. I like to buy hubs that will have 25% more capacity (or more depending on the situation) than is needed. So, if you have 3 computers, buy a 4 port hub. If you have 6, buy an 8 port, and so on. Don’t forget that an uplink port is also nice. If you run out of spaces, you can use the uplink port to link that hub with another hub. There is a problem with that though. All the computers from the first half only have one line to access the computers in the other half of the segment. That really isn’t a major concern in homes, but it’s a major concern in upstart businesses.

The positioning of the hub also plays an important role. Some people, like myself, like to have the hub close to the central computer of the network. In some cases, that might be the server. In other’s, it might be the computer that is used most by the “Computer Guy/Gal” of the house. It’s your choice where you place it, because it’s your hub. Just remember, you’ll need to buy enough cable to reach the hub from all computers that are being networked.
