Which statement describes Ethernet cables in networking?

• A. They are wireless signals.
• B. They are extremely fast over long distances.
• C. They are cheap but cover only medium distances.
• D. They use fiber optic cables.

Answer: (C)

Ethernet cables describe wired connections that carry data through physical cables, typically copper twisted-pair in everyday networks. They’re inexpensive to buy and install, making them a popular choice for homes and small offices. The practical limit for a single copper Ethernet run is about 100 meters; beyond that the signal starts to degrade and performance drops unless you add network hardware to extend the reach. That combination of low cost and a moderate maximum distance is what makes the description fit best: you get a cheap solution that works well over medium distances, but not for very long-haul links. Wireless signals aren’t what Ethernet cables use, so that option isn’t accurate. While there are high-speed Ethernet variants, copper cables don’t deliver extreme speeds over long distances on their own. And although fiber optic cables are used in some Ethernet implementations, the common Ethernet cable refers to copper; fiber requires different cables and components.
