card stacker मीनिंग इन हिंदी

When using earlier IBM keypunches, a keystroke error required the card to be ejected by pressing the Release and Register keys, the error corrected by pressing the Duplicate key until the error column was reached, typing the correct data for the rest of that card, then pressing the Release key and manually removing the bad card from the output card stacker before it was placed in the deck ( this required some practice, but quickly became an automatic action that you no longer had to think about ).
