Spooling considers disk as a huge buffer that can store as many jobs for the device till the output devices are ready to accept them. Nowadays, the most common use of spooling is printing: documents formatted for printing are stored in a queue at the speed of the computer, then retrieved and printed at the speed of the printer. Spooling also lets you place a number of print jobs on a queue instead of waiting for each one to finish before specifying the next one. Spooling is a combination of buffering and queueing.
Spooling works like a typical request queue where data, instructions and processes from multiple Applications/Implementations of Spool: Operating Systems. Spooling is a process in which data is temporarily held to be used and executed by a Generally, the spool is maintained on the computer's physical memory, buffers or the What is the difference between a mobile OS and a computer OS?.
What exactly Spooling is all about GeeksforGeeks
Operating System Properties - Learning operating system in simple and easy steps for the job gets copied into an output spool for later printing or processing .
Subsequent operations on X will update the cached copy of X, but not the external memory version of X. The files and directories at any level are contained in the directory above them.
Sammy Joshua. Buffering increases the performance of the device. Before discussing buffering, let us discuss, what is the buffer?
A dedicated program, the spoolermaintains an orderly sequence of jobs for the peripheral and feeds it data at its own rate. This is especially useful in real-time computing applications where not stalling behind concurrent operations is critical.
Spooling in Operating System and Spool Disk discussed with diagram.
For use of this term to refer to thrust changes in jet engines, see Jet engine. Namespaces Article Talk. Buffering is less efficeint than spooling. So bytes coming from the modem is accumulated in the buffer space, and when all the bytes of a file has arrived at the buffer, the entire data is written to the hard disk in a single operation.
Operating System Properties
For example, a spooler at a time may read input of one job, and at the same time, it may also print the output of another job. Subsequent operations on X will update the cached copy of X, but not the external memory version of X.
One can also write programs in low-level languages called assembly languages, although this is more difficult.
