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.
True - Ethernet is the predominant protocol found in LANs today.
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 CAT3 has been superseded and is seldom used today, but it still has uses in telephone wiring.
Two instances of networks that are integral to modern life are social media networks and the internet of things (IoT). Social media networks facilitate communication and connection among individuals and communities globally, shaping how we share information and interact. Meanwhile, IoT connects everyday devices to the internet, enabling smart homes and improving efficiency in various sectors, from healthcare to transportation. Together, these networks profoundly influence our social interactions and daily activities.
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.
Ethernet revolutionized networking by enabling reliable and high-speed data communication over local area networks (LANs). Introduced in the 1970s, it standardized how devices connect and communicate, facilitating the growth of computer networking and the internet. This technology made it easier for businesses and individuals to share resources and information, laying the groundwork for the interconnected world we live in today. Its scalability and adaptability have made Ethernet a foundational technology for networking infrastructure worldwide.
