The terms punched card, punch card,

The terms punched card, punch card, and punchcard were all commonly used, as were IBM card and Hollerith card (after Herman Hollerith). IBM used "IBM card"[11] or, later, "punched card" at first mention in its documentation and thereafter simply "card" or "cards".[12] The term punched card was generally avoided for blank cards, with other terms such as tabulating card, or tab card used.[13][citation needed] Specific formats were often indicated by the number of character positions available, e.g. 80-column card. A sequence of cards that was input to or output from some step in an application's processing was called a card deck or simply deck. The rectangular, round, or oval bits of paper punched out were called chad (chads) or chips (in IBM usage). Multi-character data, such as a name, line of an address, or multi-digit number, was stored in adjacent card columns known as a field.
