Is a graphics card also known as a video card?

When I have scrolled online it is slow and choppy (with lines). Is that caused by a faulty video card or driver? What is the best compatible video driver for a Dell Inspiron 5160 laptop computer? Does Card, Graphics XGI, XP5, 32 MB I5160 describe a video card or graphics card? Was or was not the Inspiron 5160 even configured originally with an installed video card or was it built into the motherboard?
