<P> A widely adopted family of transmission media used in local area network ( LAN ) technology is collectively known as Ethernet . The media and protocol standards that enable communication between networked devices over Ethernet are defined by IEEE 802.3 . Ethernet transmits data over both copper and fiber cables . Wireless LAN standards use radio waves , others use infrared signals as a transmission medium . Power line communication uses a building 's power cabling to transmit data . </P>
