The RJ45 connector is the standard for Ethernet networking and is designed to work with Cat5e, Cat6, and Cat6a cabling, which are common cables for supporting Gigabit Ethernet (1000 Mbps). While RJ11 is a connector typically used for telephone lines and is not adequate for Ethernet networks, and the F type connector is commonly associated with coaxial cable used in television and internet connections via a modem rather than direct PC connections. Although BNC connectors can be used for Ethernet, they are not commonly used for Gigabit Ethernet connections.
