* A low profile card is smaller then a normal PCI card as far as height is concerned. These special types of cards are required by systems using very small flex atx or ultra slim cases under 5" high (for desktops) or 5" wide (for towers).
* Book PCs generally require half height cards.
* The terms half-height, low-profile, half height, and low profile are used interchangeably and mean the same thing.
