What type of cable consists of twisted copper wires wrapped around each other?

Twisted pair cable is characterized by its construction of pairs of insulated copper wires twisted around each other. This design helps to reduce electromagnetic interference and crosstalk from adjacent wires, making it a popular choice for networking and telecommunications. Twisted pair cables come in two main categories: unshielded twisted pair (UTP) and shielded twisted pair (STP), both of which are widely used in Ethernet networks and other data transmission applications.

In contrast, fiber-optic cables use glass or plastic fibers to transmit data as light signals, which allows for higher bandwidth and longer transmission distances without interference. Coaxial cables consist of a central conductor surrounded by insulation, a metallic shield, and an outer insulating layer, commonly used for cable television and internet services. Wireless media refers to communication methods that do not require physical cabling, primarily relying on radio waves or infrared signals for data transmission. Thus, the distinct characteristics of twisted pair cable make it the correct answer for this question about the type of cable composed of twisted copper wires.
