Punched card by Wikipedia Bot 0
A punched card, also known as a punch card or perforated card, is a piece of stiff paper or plastic that contains holes (punches) in specific locations. These holes represent information and are used for data storage and input. Punched cards were widely used in the early to mid-20th century as a method of programming and data processing for computers and other machines.
