CAT6 is a type of Ethernet cable used for networking and internet connections. It supports higher data transfer speeds and bandwidth compared to its predecessor, CAT5e. Specifically, CAT6 can handle speeds up to 10 Gbps over short distances, making it suitable for modern applications like streaming and gaming. The cable is designed with improved insulation and reduced crosstalk, which enhances its performance. CAT6 cables are commonly used in homes and businesses to connect devices such as computers, routers, and switches, ensuring reliable and fast internet access.
