Which of the following are characteristics of coaxial network cable?

1. It is thinner than Ethernet cable; It has a fiber optic core

2. It uses two concentric metallic conductors; It has a conductor made from copper in the center of the cable

3. It is flexible; It supports wireless transmission

4. It cannot carry audio signals; It is less expensive than fiber optic

The correct answer is: It uses two concentric metallic conductors; It has a conductor made from copper in the center of the cable

Coaxial network cable is characterized by its structure, which includes two concentric metallic conductors. The central conductor is typically made of copper, which acts as the primary medium for transmitting electrical signals. The outer conductor, usually a metal shield, provides additional protection against electromagnetic interference and helps maintain the integrity of the signal over longer distances. This specific design allows coaxial cable to effectively transmit data, making it suitable for various applications, including cable television and Internet connections. The combination of these two conductors is a defining feature that sets coaxial cable apart from other types of network cables, such as twisted-pair or fiber optic cables. Other options do not correctly represent the characteristics of coaxial network cable. For example, coaxial cable is generally thicker than Ethernet cable, it does not contain a fiber optic core, it is not particularly flexible compared to other cables like twisted pair, and it cannot transmit wireless signals. Additionally, coaxial cable can indeed carry audio signals, and while it can be less expensive than fiber optic options, it does not serve as the primary reason for its function or characteristics.
