Card image is an archaic term for a character string, usually 80 characters in length, that was, or could be, contained on a single punched card. IBM cards were 80 characters in length, UNIVAC cards were 90 characters. A punched card typically held multiple data fields, some numeric, some alphabetic. Many data formats, such as the FITS image file format, still use card images as basic building blocks -- even though punched cards are now mostly obsolete.
Famous quotes containing the words card and/or image:
“There is undoubtedly something religious about it: everyone believes that they are special, that they are chosen, that they have a special relation with fate. Here is the test: you turn over card after card to see in which way that is true. If you can defy the odds, you may be saved. And when you are cleaned out, the last penny gone, you are enlightened at last, free perhaps, exhilarated like an ascetic by the falling away of the material world.”
—Andrei Codrescu (b. 1947)
“If the study of his images
Is the study of man, this image of Saturday,
This Italian symbol, this Southern landscape, is like
A waking, as in images we awake,
Within the very object that we seek,
Participants of its being.”
—Wallace Stevens (1879–1955)
