Punch cards were one of the primary methods of storing and retrieving data Storage Of Information: Punch cards we primarily used to put data in the mainframe computers. Punch Cards were a cheap mean and reasonable device since Input Of Data & Information: ![]() Punch cards were a primary storage device in the early 1900s which were later replaced by modern means of storing information by the 1960s. The use of punch cards diminished after the development of magnetic strips. To save information and store, essential programs punch cards were used. In the early days of computers, the old devices were not advanced enough to store and process large amounts of information like the devices of modern times. The code on the punch card was similar to the binary system. In the case of errors and omissions, the whole card must be printed again. The top of the card said what each card contained so that it could be understood what was saved and stored on a certain type of card.
