Which type of cable typically contains one central core for data transmission?

The correct answer, coaxial cable, is specifically designed to transmit data over a single central core surrounded by insulation and a shield. This structure allows coaxial cables to effectively carry high-frequency signals with minimal interference, making them ideal for both data networking and video transmission. The central core, typically made of copper, serves as the primary conductor for the transmission of electrical signals, while the outer shielding helps protect against external electromagnetic interference.

Twisted pair cables also contain cores, but they comprise multiple twisted wires within a single cable rather than a single central core. These are commonly used in telephone and Ethernet networks.

Mechanical Transfer Register Jacks (MTRJ) and Lucent Connectors (LC) refer to specific types of fiber optic connectors, which do not utilize a central core in the same sense as coaxial cables. Instead, they consist of fiber optic strands that transmit light signals rather than electrical signals. Thus, while they facilitate data transmission, they operate on fundamentally different principles compared to coaxial cable.
