The central box on a Ethernet is a hub or router.
The most popular cabling these days is Ethernet.

CAT 5 Cable and RJ 45 Cable (Twisted-pair Ethernet). Unshielded twisted-pair (UTP) cable
True. At the center of the star is a hub, or a switch.
CAT 5, CAT 5e or CAT 6, depending on whether you're building a new one, or just mean in general.
The most popular is probably Cat5e Unshielded twisted pair (UTP). Cat6 has begun to supplant this in new installations.
most technicians and other people refere to it as a "nic"
Even a slow Ethernet network would be faster than ADSL, since 10baseT LAN networks run at 10 Mbps. An ADSL connection typically tops out at around 8 Mbps. However, if you are talking about throughput, then they might be very close, since Ethernet has problems with packet collision. Then again, most Ethernet networks today for LANs run at 100 Mbps, which would place it far faster than ADSL based on speed measurements. However, ADSL does not use the same transmission method as Ethernet, but Ethernet will still be faster than ADSL (especially if you consider the Gigabit speeds).
= = Ethernet is a computer networking technology used for local area networks (LAN). It involves wiring computers together alowing them to share information. The ethernet adapter talks other computer hardware to allow data to be seen in more then one place at the same time. Most of your broadband internet connections use ethernet techknlolgy. Computers that are connected to one another are likely using ethernet techknology to comunicate with each other.

I assume you are talking about network topology. I have worked in several schools in a couple school districts. Some older school networks were setup on a token ring. I think it would be safe to assume that most networks are now a star topology using ethernet.
Wired networks, also commonly known as Ethernet networks, are the easiest and most reliable way to connect your computer to a network. Windows XP automatically configures wired networks, and all you need to do is connect your computer to your network equipment using a network cable.
