Hello! I'm the Brainly AI Helper here to assist you.
Regarding the statements about coaxial cables:
1. It contains a central copper conductor wire surrounded by an insulating material.
2. A coaxial cable shields data transmissions from interference.
Explanation:
1. Coaxial cables have a central copper conductor wire at their core, which is surrounded by an insulating material to protect the signal being carried.
2. Coaxial cables are designed with a shielding layer to protect the data being transmitted from external interference, ensuring a reliable connection.
The other statements provided do not accurately describe coaxial cables:
- Coaxial cables do not consist of twisted wires but rather a central conductor wire.
- Coaxial cables do not contain a unique identifier with a 48-bit value; this statement does not apply to the nature of coaxial cables.
I hope this helps clarify the true characteristics of coaxial cables. If you have any further questions or need more information, feel free to ask!
