SPOOLING stands for Simultaneous Peripheral Operations Online. A Spooler program has one job: to remember, keep in order, and process 'jobs' in the order that it received them.
SPOOLING comes into play regarding printing. Let's say you have these items you want to print:
Without Spooling, you would have to WAIT until one job is done before you click print on the next job. WITH spooling, your computer remembers "What am I supposed to print next?" When one task finishes, the next one starts automatically.
This is important with companies. If a payroll department must print 100 paychecks, it can take 1 click to start the process, and the Spooler keeps track of the jobs so Suzy Q does not get Joe Blough's paycheck amount and Joe Blough does not get his boss's paycheck. The printer can keep working non-stop as long as it has paper and ink.
Spooling is putting jobs in a buffer area, whether in memory or on disk, where they can be accessed when a device is ready. For example, print jobs are spooled to a buffer to be printed when the printer is ready.
A spooled string of genes packaged in a single unit is called a chromosome. A chromosome is a structure of DNA, RNA, and protein which are found in cells.
Spooled Documents are simply documents that are waiting to be printed. When you tell your computer to print a document there is a process that it must go through. If you tell it to print another one before the first one is done printing it will take it's place in line (or be spooled up) waiting for the printer to complete the previous task.
