What type of cable is characterized by four twisted pairs used in structured cabling for computer networks?

The cable characterized by four twisted pairs used in structured cabling for computer networks is commonly known as Category 5 cable, often abbreviated as CAT 5. This type of cable is widely used for Ethernet networks and supports data rates up to 100 Mbps over distances up to 100 meters. The twisted pairs help reduce crosstalk and electromagnetic interference, which enhances the performance and reliability of data transmission.

While other categories such as CAT 4 and CAT 3 also involve twisted pairs, CAT 5 is the standard that became prevalent for higher-speed networking due to its ability to handle more bandwidth and support more complex network environments. Category 6, while also consisting of four twisted pairs, is an advancement over CAT 5 and provides even higher performance, supporting data rates beyond 1 Gbps. However, in this specific context of the question, CAT 5 is recognized as the cable type specifically known for four twisted pairs used effectively in structured cabling.
