Build an Ethernet network
If you need to support a dozen or more computers and you have to squeeze every bit out of your LAN, use traditional 100BaseT Ethernet equipment and cables. Gigabit Ethernet may be faster, but the equipment remains relatively expensive, both for small and large offices.
Don't forget that in addition to your Ethernet cables, you'll also need a router with an integrated Ethernet switch and possibly additional switches for larger networks. Some routers include print servers or USB ports that let you attach external hard drives to your network. Such features make it easy to back up data and share resources from any machine.
Finally, you'll want to hide all these cables so they don't create an eyesore. Here's your plan:
Ethernet tips:
Make your own cables. It's easier and cheaper than you think, and it means that
every cable will be just the right length. The first step is to get a spool
of Cat-5 cable, a crimping tool (see image), and a bunch of modular RJ-45
plugs, available at many hardware stores. Cut the cable to a little longer
than you'll need and use the crimping tool to strip off a half-inch of the
cable's outer cover without damaging the wires below. Carefully line up and
pinch the eight wires between your thumb and forefinger, then gently push
them into the plug. Finish by squeezing the crimping tool's handle. Repeat
at the other end and test the cable with a connection that you're sure works.
