What type of networking uses physical cables to connect devices?

• A. Wired
• B. Wireless
• C. Infrared
• D. Satellite

Answer: (A)

In networking, using physical cables to connect devices is called wired networking. It relies on tangible media like copper Ethernet cables or fiber optic cables to carry signals. This approach usually offers stable connections, higher potential throughput, and lower latency with less interference from other wireless devices, though it requires running cables and can be limited by distance or installation costs. The other options involve wireless or non-local media: wireless uses radio waves with no physical cable, infrared relies on infrared light and typically needs line-of-sight over short distances, and satellite links signal via a satellite and back down to Earth, not a local wired path.
