What Is an Ethernet Modem?
An Ethernet modem is a device used to connect a computer to the Internet. Ethernet modems use broadband technology that operates at far higher speeds than older, dial-up methods. Created in the 1970s by Robert Metcalfe, and based on an earlier system known as Alohanet, Ethernet technology originally had theoretical data transfer rates of up to ten megabits per second (Mbps). Current gigabit Ethernet modem technology allows speeds of up to 1000 Mbps. The term Ethernet is a reference to the passive substance ether, which was once thought to pervade all things. In theory, ether carried light throughout the universe. Ethernet, meanwhile, uses the passive medium of cables to transmit data throughout its network.
