The Easiest Ethernet LAN Segment 2 of 5


 



In my case, for this exercise, the first of these computers was a Compaq laptop, and here is a picture of its Ethernet connector, clearly visible along the back edge. Note that the connector has two little Light Emitting Diodes: one is called the "Link Light", indicating that there is an Ethernet connection, and the other is called the "Ethernet Activity Light", which flashes whenever the Ethernet interface is sending or receiving data.



The second of the two computers is a Hewlett Packard laptop. Like the first, it also has a modern Ethernet connector; this one visible on the side. And just like the Compaq, it also has two LEDs. The one on the left indicates data activity, and the one on the right is a link light, indicating that a hardware connection is active.
