1 gen 1890 anni - Punch card

Descrizione:

A punched card or punch card is a piece of stiff paper (approximately equivalent to 100# card stock) that can be used to contain digital data represented by the presence or absence of holes in predefined positions.

The punch card was used in early computers to technically store information. They are now rarely used or found as many of the teenagers may have not been exposed to this device. Punch cards were the primary method of storing and retrieving data before. But today, we are exposed to hard drives, flash drives, CDs, and more.
