Thin ethernet is generally our least reliable form of ethernet. Virtually all modern machines and ethernet adapters support 10base-T ethernet and many support it exclusively. Although you can only connect a single machine directly to your outlet, it is possible for you to purchase a 10base-T hub to connect multiple devices to a single activated outlet. With shared 10base-T, all traffic coming from or going to any machine on your segment will be on your connection, thus lowering your maximum connection speed. With switched 10base-T, the 'switch' will only put traffic on your connection that you need to see.
Extraneous traffic is eliminated.
