LAN Card
Note:
While transfering the data, the 'Act' LED emits light
to indicate a ready state and the link indicators '10 Link' or '100 Link'
specifies the current line transmission speed.
Depending on the 10Base-T/100Base-T connections to unshielded twisted-pair
(10Base-T, UTP) or unshielded twisted-pair (100Base-T, Catagory 5),
the transmission speed will be auto-detected.
