Which type of network cable is used for connecting a computer to a switch?

Correct answer: Straight-through cable

Option A is correct because a straight-through cable connects devices of different types, such as a computer (DTE) to a switch (DCE), with each wire connecting to the same pin number on both ends, following the same wiring standard on both connectors. Option B is wrong because fiber optic cable uses light transmission over glass or plastic strands and is typically used for long-distance or high-bandwidth backbone connections, not standard computer-to-switch links. Option C is wrong because coaxial cable is associated with older bus topologies and cable broadband, not modern Ethernet connections between endpoint devices and switches. Option D is wrong because a crossover cable is used to connect two devices of the same type, such as two computers directly or two switches together, by reversing the transmit and receive pairs.
