punched cards
Punched cards are a form of data storage that were commonly used in early computer systems. They consist of stiff cards with holes punched in them to represent data. These cards were used to input and store information, which could then be processed by computer systems. Punched cards played a significant role in data processing during the mid-20th century, allowing for the automation of tasks like tabulation and data analysis.
