Which statement about wired and wireless networks is most accurate?

Which statement about wired and wireless networks is most accurate?

• A. Wireless uses radio signals (Wi-Fi) and is convenient but can suffer from interference and range limitations.
• B. Wired uses physical cables (Ethernet) and is typically faster and more stable.
• C. Wired uses radio signals.
• D. Wireless uses physical cables.

Answer: (B)

Understanding this topic comes from how data travels: through physical cables or through air via radio waves. A wired connection uses a physical cable such as Ethernet, which provides a reliable path with consistent performance. Because the signal stays inside the cable, there is less exposure to environmental interference, leading to higher and more stable throughput in most situations. Wireless connections, using radio signals like Wi‑Fi, offer mobility and easier setup, but they’re more susceptible to interference from walls, other devices, and distance, which can impact speed and reliability. The statement that wired uses physical cables and is typically faster and more stable captures the main, broadly true distinction. The other options touch on wireless aspects or misstate how wired and wireless work, but they don’t convey the stronger, general advantage of wired networks.
