It’s also commonly used with broadband Internet, connecting the cable modem or DSL modem to a wired router or a wireless router, for example. To use Ethernet with your computer, it will need an Ethernet card, which is an expansion card that provides an Ethernet jack and the hardware and software needed to transmit over the Ethernet network. If you look at the connector on the end of an Ethernet cable, called an RJ45 or an 8P8C modular connector, you’ll notice that the RJ45 looks a lot like a telephone line connector, but the Ethernet connector is larger and wider. An Ethernet cable has male RJ45 connectors on both ends, and the cables can be anywhere from a few feet to hundreds of feet long (or one to 70 meters).
