What connector is used to connect a wired router to an Ethernet network?

The right choice is indeed the RJ-45 connector, which is a standard connector used for Ethernet networking. RJ-45 plugs into an Ethernet port and supports the transmission of data over local area networks (LANs). This type of connector is designed to accommodate the wiring used in Ethernet cables, specifically twisted pair cables, facilitating high-speed data transfer between devices on a network.

In the context of connecting a wired router to an Ethernet network, the RJ-45 connector provides the necessary interface to allow data communication between the router and other network devices, such as computers and switches. The design of RJ-45 is robust and supports multiple pin configurations, which are essential for effective data transmission.

While USB connectors are commonly used for connecting peripheral devices to computers, they are not compatible with Ethernet networking for routers. RJ-11 connectors are primarily used for telephone connections and are not suited for Ethernet applications because they have fewer pins and do not support the specific data transmission protocols of the Ethernet standard. HDMI, on the other hand, is used for transmitting high-definition video and audio, not for networking purposes. Thus, the RJ-45 connector is the appropriate choice for connecting a wired router to an Ethernet network.
