### Punch Card in- Jacquard's Loom

The Jacquard loom is a mechanical loom, invented by Joseph Marie Jacquard in 1801 that simplifies the process of manufacturing textiles with complex patterns. The loom is controlled by punched cards with punched holes, each row of which corresponds to one row of the design. Multiple rows of holes are punched on each card and the many cards that compose the design of the textile are strung together in order. Its entire operation was under the control of a program and its weaving process was automatic. The Jacquard loom was the first machine to use punched cards to control a sequence of operations. Although it did no computation based on them, it is considered an important step in the history of computing hardware. With the invention of punched cards, the era of storing and retrieving information started.
