FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The Jacquard mechanism, invented by Frenchman Joseph Marie Jacquard and first demonstrated in 1801, simplified the way in which complex textiles such as damask were woven. The mechanism involved the use of thousands of punch cards laced together.

Detailed explanation-2: -Punch cards have been used to control the operation of machinery from the early nineteenth century, when the Frenchman Joseph Marie Jacquard patented an attachment to a loom in which a series of punched cards (one for each row of the weave) controlled the threads raised in producing the pattern.

Detailed explanation-3: -The punched cards controlled the actions of the loom, allowing automatic production of intricate woven patterns. The punched-card idea was adopted later by Charles Babbage about 1830 to control his Analytical Engine, and later still by Herman Hollerith for tabulating the 1890 USA census.

Detailed explanation-4: -These are machines that that punch holes in stiff paper cards in selected positions within fixed rows and columns to record information that can be read back or interpreted later by other machines called card readers, which are connected to or integrated with tabulators, computers, or other devices.

Detailed explanation-5: -Punched cards date back to the late eighteenth and early nineteenth centuries when they were used to “program” cloth-making machinery and looms. In the 1880s and 1890s, Herman Hollerith used them with his tabulators-a core product of what would eventually become IBM.
