You seem like a home-user, so I am going to assume that this 10/100 Network Adapter is an Network Interface Card (NIC). Basically you plug an RJ-45 CAT5 or CAT6 (a fat phone cord) into the slot on the NIC and plug the other end into another network device, usually a modem or some sort of switch. You can't plug it directly into another machine unless you get a special cable called crossover cable.

So basically if you want to connect to another computer then you either need a switch/router (the best way if you want multiple computers connected to one internet connection) or you can directly network them together with the crossover cable. There are actually other ways of sharing network connections but they are typically more difficult to setup.

You should research home networking to find some networking solutions.

10/100 Network Adapter this means the adapter can transfer at both 10 and 100 mbps.
