What is an example of a spooled device
A A line printer used to print the output of a number of jobs
B A terminal used to enter input data to a running program
C A secondary storage device in a virtual memory system
D A graphic display device
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:
- A funny picture (which can take time to print);
- Your 5 page paper for English Class;
- A letter you wrote to your grandma
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.
