Punched cards were once common in data processing and the control of automated machines. Punched cards were widely used in the 20th century, where unit record machines, organized into data processing systems, used punched cards for data input, output, and storage. [3] [4] The IBM 12-row/80-column punched card format came to dominate the industry.
A single program deck, with individual subroutines marked. The markings show the effects of editing, as cards are replaced or reordered. Many early programming languages, including FORTRAN, COBOL and the various IBM assembler languages, used only the first 72 columns of a card – a tradition that traces back to the IBM 711 card reader used on the IBM 704/709/7090/7094 series (especially the ...
Punch cards were stepped across the punch one column at a time, and the appropriate punches were activated to create the holes, resulting in a distinctive "chunk, chunk" sound as columns were punched. Both machines could process 51-, 60-, 66-, and 80-column cards. [20] The 026 could print the punched character above each column.
An IBM 80-column punched card of the type most widely used in the 20th century IBM 1442 card reader/punch for 80 column cards. A computer punched card reader or just computer card reader is a computer input device used to read computer programs in either source or executable form and data from punched cards.
Edge-notched cards were used for course scheduling in some high schools and colleges. [11] Keysort cards were also used in World War II codebreaking. The Stasi used edge-notched cards (German: Kerblochkarteikarten) from 1965 to index information including details of staff, crimes, people under surveillance, and vehicles. Cards often stored ...
