The
punched cards reflected the rug motifs, wanting us to believe that everything that has order has music.
* The first tape drives implemented a 7-track recording format on an eight-inch diameter reel and had a linear recording density of 100 bits per inch and had a capacity of 1MB or the equivalent of 12,500
punched cards.
To be sure, devising the
punched card required considerable intelligence and ingenuity in the first place, but once the cards were designed and in place, the machine did not need brains; it worked automatically.
Most mechanical engineers, if they are involved in computer applications, will sooner or later read a statement to the effect that Joseph Jacquard's punched-card controller for textile looms was the "beginning of the computer age." The remark is usually accompanied by a bit of 19th-century history, but no explanation as to how he used a
punched card to control a powerful machine like a loom in the absence of electronics.
Or you could buy the RAMAC for $167,850 with
punched card output or $189,950 with printed output.
Beginning with a
punched card and soon followed by the first magnetic tape drive, the IBM 726 in 1952, and the first disk drive, the IBM Ramac 350 in 1956, the storage industry and its hierarchy was born.
I assume the company you worked for has something called "time
punched cards"?
She was Lord Byron's daughter and worked alongside Charles Babbage preparing the
punched cards for his difference engine.
What made his machine unique was the use of
punched cards that, when strung together, produced the same pattern with each use, Shortly thereafter, mathematician Charles Babbage recognized the potential of Jacquard's idea and put it to use in a computer that he called the Analytical Engine.
