An Ethernet connection describes computers that communicate through what medium?

• A. Radio signals
• B. Wired connection
• C. Satellite
• D. Infrared

Answer: (B)

Ethernet is about sending data over a physical wired path. In most local networks you connect computers with cables—typically copper twisted-pair cables like Cat5e or Cat6, or fiber optic cables for higher speeds. These cables carry the electrical or light signals that encode the data, using standardized Ethernet rules to manage how devices share the network. While wireless or other media (radio, infrared, satellite) exist for different kinds of links, the standard Ethernet connection uses a wired medium.
