Spooling

Have you ever seen a big machine that prints lots of papers very quickly? That big machine needs to have lots of papers that it can print. But what if the big machine can't print as fast as you need it to? That's where spooling comes in!

Spooling is like having someone helping you by getting all the papers ready for you to print. This someone, called the spooler, takes all the papers you want to print and puts them in a special place called a spool. The spool makes sure that the papers are organized and ready to be printed whenever the printer is ready for them.

So when the big machine is done printing a paper, it asks the spooler for the next paper that needs to be printed. The spooler gives the big machine the paper it needs, and the big machine can print it without any delays.

Spooling helps big machines print lots of papers quickly and efficiently. It's like having a helper to get all the papers ready for you so you can focus on printing them!
