In a network interface card, which component typically has two lights?

Explanation:
Status indicators on a network interface card are provided by LEDs. Two lights on the Ethernet port are common, one to show the link status (whether a connection is present and at what speed) and one to indicate data activity (transmitting or receiving). The lights blink or stay solid to give quick, at-a-glance feedback about network activity and connection. A card slot is simply a connector, a cable is the medium that carries signals, and an antenna is used with wireless devices—none of these are the light indicators used on NIC ports.
