The main way to tell which expansion card is the video card is to look at the plug. If it has a VGA socket, a display port socket, HDMI, etc., then you will know it is a video card. You may identify some of the chips on the card as being RAM, or you might find a fan on it, but these features are not exclusive to video cards. If that is the place where you plug your monitor, then it is a video card, unless of course you are plugging directly into the motherboard.

An integrated video card is "integrated" into the motherboard. That means the motherboard has a video card built in. A "discrete" video card means that you have a separate video card, one that typically plugs in to one of the expansion slots.
VGA is ("Video Graphics Array/adapter") the term for a video card or other video adapter (such as an integrated one). AGP is a standard for video card expansion slots. Basically these are slots (designed for graphics adapters) that operate at a much higher throughput than PCI slots (normal, shoter, usually white expansion slots for other expansion cards). These come in a few versions: 2X, 4X, and 8X are the big ones right now. If you are interested in upgrading your video card (or lack thereof) you need to know what version your motherboard supports (an old one might support 2X /4X) and then you can decide what version of AGP to look for in a video card. also note that there is a new standard for video cards called PCI-express (PCI-x16). Currently, most of the newest video cards and motherboards are designed on this. later
Expansion Slot is just like port into which expansion card can be inserted. In otherwords port is female and card is male.
