Connecting Devices Directly with Crossover Cables

What type of cable has cross-connected TX/RX data lines?

a. Crossover Cable
b. Coaxial Cable
c. Fiber Optic Cable
d. Patch Cable

Answer:

A cable with cross-connected TX/RX data lines is a crossover cable, used for connecting similar networking devices directly.

A cable with cross-connected TX/RX data lines is known as a crossover cable. This type of cable is used to connect two similar devices directly, such as connecting two computers without using a switch or hub, by crossing over the transmit and receive lines. This allows the connected devices to communicate directly and is a practice commonly seen in older networking setups or for certain troubleshooting scenarios.

For comparison, coaxial cables consist of two concentric conductors separated by insulation, commonly used in cable TV or other audiovisual connections. On the other hand, fiber optic cables are designed for long-distance and high-performance data networking and are made from fibers of glass or plastic that transmit light signals for telephone, internet, and cable TV signals, offering significant advantages such as high bandwidth, low loss, and reduced crosstalk.

Overall, a crossover cable stands out in the context of networking for its specific use in directly connecting networking devices by cross-connecting TX/RX data lines.
