PC Card - Card Information Structure

The card information structure (CIS) is information stored on a PC card that contains information about the formatting and organization of the data on the card. The CIS also contains information about:

  • The type of card
  • Supported power supply options
  • Supported power saving features
  • The manufacturer
  • Model number
  • and so on.

When a card is unrecognized it is frequently because the CIS information is either lost or damaged.

Famous quotes containing the words card, information and/or structure:

    What is the disease which manifests itself in an inability to leave a party—any party at all—until it is all over and the lights are being put out?... I suppose that part of this mania for staying is due to a fear that, if I go, something good will happen and I’ll miss it. Somebody might do card tricks, or shoot somebody else.
    Robert Benchley (1889–1945)

    Phenomenal nature shadows him wherever he goes. Clouds in the staring sky transmit to one another, by means of slow signs, incredibly detailed information regarding him. His inmost thoughts are discussed at nightfall, in manual alphabet, by darkly gesticulating trees. Pebbles or stains or sunflecks form patterns representing in some awful way messages which he must intercept. Everything is a cipher and of everything he is the theme.
    Vladimir Nabokov (1899–1977)

    Women over fifty already form one of the largest groups in the population structure of the western world. As long as they like themselves, they will not be an oppressed minority. In order to like themselves they must reject trivialization by others of who and what they are. A grown woman should not have to masquerade as a girl in order to remain in the land of the living.
    Germaine Greer (b. 1939)
