|The Hollerith Code - The Punchcard Alphabet - |
Herman Hollerith created a code to be used to indicate the letters of the alphabet, numbers and the special characters of the English language. He did this around 1880.
If you have been to a computer museum, or are as old as I am, you may have seen a computer punch card. These cards were read by computers. The holes that were punched in them indicated letters, numbers or special characters. The punched cards were the standards in data processing from before 1900 until the 1970s.
In the standard punch card had 80 columns and 12 rows. Each column was numbered 12,11,10 or 0,1,2,3,4,5,6,7,8,9. By combining different combinations of whole punches, you could spell out words or numbers. (Hint: 12 & 1 = A, 11 & 1 = J, 10 & 2 = S)
This quiz is to see if you know this code.
The picture to the left is of one of those punch cards using the Hollerinth Code.
