Definition - What does Ethernet Adapter mean? An Ethernet adapter is a piece of hardware that allows a device or workstation to access an Ethernet connection. Ethernet adapters can be add-ons that go into an expansion board, or they can be directly installed in the motherboard of a computer or device.
The MAC address is used on the physical transfer. An ethernet adapter does not know anything about IP. So the ethernet adapter uses the MAC address to address the receiver of the data packet. If the ethernet adapter would know anything about IP then we have to upgrade all our firmware to switch to a new protocol (like IPv4 to IPV6).
