Industry standard for computer-to-computer interconnection
Specified by IEEE 802.3 standards
Speeds from 10 Megabits/second to 10 Gigabits/second
Cabling and Power
Usually uses twisted pair wire star-connected to hub, basic maximum distance 100 meters for a single cable
If longer cable runs needed, optical fiber can give effectively unlimited distance, but can't carry power.
Can carry limited -48 volt power
Wireless variant available, still high speed
