No, today virtually all networks use some variation of a star topology. It's far less subject to failure.
Repeaters are usually used in coaxial based ethernet networks. For this purpose they are used to extend the length of a network segment. For example, in a 10base2 ethernet network the maximum length of a segment is 180 meters. A repeater could join two segments together to increase the length of the network and the number of clients in the network. In today's modern networks you will see neither coaxial networks nor repeaters in a LAN. Repeaters are used for DSL transmissions, but not for LANS.
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).
Today, Ethernet LAN has one competing LAN technology: WLANs.
In the 1990s CAT3 was used in 10BASE-T Ethernet, token ring and ATM25 networks. It was also used in 100BASE-T4 Ethernet technologies which employed all 4 pairs to achieve greater bandwidth. CAT3 has been superseded and is seldom used today, but it still has uses in telephone wiring.
True - Ethernet is the predominant protocol found in LANs today.
No, not at all. That's by far the most common today, but at one time it was much more common to run either "thinnet" or "thicknet", both of which used coaxial cables.
