I've been wondering what line card is?
Is it like NIC on interface?
Thank you. I'm learning CCNP. Hope I can move on my learning with the help of this community.

It's often used as a reference to a chassis switch's multiple port module cards. Number of ports vary, but unlike module cards, line cards usually contain a good number, for instance 24 to 96 Ethernet copper ports. There's not a clear demarcation between a port module card and a port line card, but again, line cards are generally larger. Also, the term is informal.
An example of a "line card" (although not its official name), might be seen in figure 1 (and others), in http://www.cisco.com/c/en/us/products/collateral/switches/catalyst-6500-series-switches/product_data_sheet0900aecd8017376e.html.

It is a card that plugs into a chassis.

May you give an image link of a line card? Thank you very much.

In the context of telephony a line card is an expansion card found in mid-range and enterprise class PBX chassis. Line cards are distinct from management cards and service cards in that generally they are used to terminate the connection to an end client device. As such, they usually perform the kinds of services you would expect with that role; Ring voltage generation, DTMF decode, loop start detection, on hook/off hook detection, etc.

Alas, I'm unable to rate your post, which I believe deserves a 5.
What you describe, very likely tells why Ethernet chassis cards, are often called "line cards" because they likely physically much appear like a Telco chassis (telephone) line card.
PS:
Ah, after adding this post, I was able to rate your post.

Sounds likely to me. It's one of those terms, like "Call Manager", that is no longer entirely accurate, but hangs around due to trade use and similarity to current nomenclature.
Here's a picture of a line card in a popular old small business class PBX. In an enterprise class PBX the cards would have much higher port densities and would therefore look more like a network module or WIC card.
