Standards that describe the performance of twisted-pair (LAN/Ethernet) cables, distinguished by a category number.
For example, Cat5e supports up to 1 Gbps, while Cat6 supports 1 Gbps (and up to 10 Gbps under the right conditions)—higher categories generally offer greater speed, transmission distance, and noise resistance. When wiring a network, you need to choose a category that matches the required communication speed.
