What type of cable is commonly used for networking?

Ethernet cable is the most commonly used type of cable for networking due to its widespread compatibility and performance in local area networks (LANs). Ethernet cables, typically categorized as Cat5e, Cat6, or higher, are designed to transmit data at high speeds over relatively short distances, which makes them ideal for connecting devices like computers, switches, and routers within a network. They support various networking standards and provide reliable and efficient communication, making them the backbone of modern networking infrastructure.

Fiber optic cables, although used in networking, are more specialized. They utilize light to transmit data over long distances with minimal loss and interference, but they are often more expensive and less common for typical home or small business networking setups. Coaxial cables are primarily used for cable television and internet services by cable providers rather than for standard networking. Serial cables are generally used for communication between computer systems or devices and are not typically employed for local area networking purposes. Thus, Ethernet cables are the preferred choice for creating networks due to their advantages in speed, efficiency, and ease of use.
