In 1725, Basile Bouchon used punched holes in paper tape to control looms and create more consistent, elaborate weaves.
The idea was further advanced by Herman Hollerith who developed punch card data processing technology for the 1890 US census.
"Often more than a hundred users would share access to a single computer.”

Before the advent of desktop computers, access to computers was both expensive and limited. Often more than a hundred users would share access to a single computer.
Programmers would “save” their programs on a series of punched cards that allowed up to 80 characters per card; though commonly only 72 of those could be used for the actual program.
A single hole would denote a digit and combinations of two or three holes were used for letters and special characters. The more sophisticated machines would provide a translation across the top of the card.
