What type of cable is typically used for Ethernet connections?

• A. Coaxial cable
• B. Fiber optic cable
• C. Twisted pair cable
• D. Shielded cable

Answer: (C)

Twisted pair cable is the most commonly used type of cable for Ethernet connections due to its effectiveness in transmitting data and its cost efficiency. This cable consists of pairs of wires twisted together, which helps to reduce electromagnetic interference and crosstalk, ensuring a clearer signal over distances commonly encountered in networking environments. The two main categories of twisted pair cables used in Ethernet are Category 5e (Cat 5e) and Category 6 (Cat 6), both of which support high-speed data transmission necessary for modern networking needs. Coaxial cable, while an important type of cable in telecommunications and cable television, is less common for Ethernet connections. Meanwhile, fiber optic cable offers high-speed data transfer and is used in some networking scenarios, especially over long distances; however, it is typically more expensive and complex to install than twisted pair cables. Shielded cable, while it reduces interference and is sometimes employed in specific environments prone to electrical noise, is not the standard for most Ethernet applications. Twisted pair cables offer a balance of efficiency, ease of use, and performance that has made them the go-to option in Ethernet networking.
