How do you suppose does an input spooling system designed to read punched cards from a card reader operate?
What will be an ideal response?
First the deck of punched cards is spooled to a disk file.Then,as the program executes, it reads the card images from the disk much faster than it could from the card reader. The presumption is that the input spooling is completed before the program executes, so that the card images will be available as the program needs them. In the interim, while the cards are being spooled to disk, the program is performing other tasks. Although punched cards are not used today, the spooling principle illustrated here is still valid.
