The basics as it is already described.  To be more specific, we need to know the card type.  And this can change between cards and vendors
But, in general;
1. Power Light - The card is getting power
 2. Link Light - The card is receiving Data
 3. Data Light - The card is receiving Data
 4. Connectivity Light - The card is connected

Really al you are looking for is the data and link to be blinking, that says they are talking on the network.

I've generally seen only two lights on NICs: a link light that shows that your Rx lines are connected to the Tx lines on the device on the other end of the cable (the color will typically show the speed); and a Data light that flashes when there is data being sent or received.

Read here http://www.mcmcse.com/comptia/network/network_interface_cards.shtml

Connectivity light is generally the network cable is connected and is OK.  But read the link above.  Note the Link light is sometimes known as  the Connectivity light as described as No 4.

And the Data light indicates a data transfer either to or from the NIC.

But different manufacturers may have different naming schemes.

This sounds like a homework question, and there are rules here about that... We aren't here to do this for people.  
If not, can you explain why you're asking?
