- output abstract "A punched card reader or just card reader is a computer input device used to read executable computer programs, source code, and data from punched cards. A card punch is an output device that punches holes in cards under computer control. Sometimes card readers were combined with card punches and, later, other devices to form multifunction machines.Most early computers, such as the ENIAC, and the IBM NORC, provided for punched card input/output. Card readers and punches, either connected to computers or in off-line card to/from magnetic tape configurations, were ubiquitous through the mid-1970s.Punched cards had been in use since the 1890s; their technology was mature and reliable. Card readers and punches developed for punched card machines were readily adaptable for computer use. Businesses were familiar with storing data on punched cards, and keypunch machines and their operators were widely employed. Punched cards were a better fit than other 1950s technologies, such as paper tape, for many computer applications as individual cards could easily be updated without having to reproduce entire files.".
