10-Base what?

10Base2, also known as Coaxial BNC

To implement this particular network, all you need is enough coaxial cable to daisy chain all of the computers together. Each computer is connected to the cable with through a simple T-connector (one end goes to the network card, the others to the incoming and outgoing cables). To create a daisy chain, simply use cable to connect one computer to another. The first and last computers on the chain still require T-connectors, and an additional end-piece called a 50-ohm terminator. To add another computer to the network, just connect the computer to one end of the chain, making sure that the first and last computers have terminators attached.

10BaseT, also known as RJ45 twisted pair

10BaseT is a more efficient, yet generally a more expensive and less scaleable solution than 10Base2, especially in regards to a simple in-house LAN. Basically, each computer on the network runs a length of cable to a central hub, which functions to pass the network traffic through each computer. Using 10BaseT, there is no need to string every computer to another system, and removing a computer from the network is easy, since there's no chain to break.
