advantage of spooling
Batch file programming is dos based programming you have to use dos commands .It is very good to perform some repetitive task in computer programming is easy you should only know the dos commands.
It is not necessary (nor possible) in C programming.
rem is a comment that is only seen if you edit the batch echo actually is printed when the batch is running
His expertise was in designing aircraft, not actually flying them. Lacking any programming experience, they sought out someone with the necessary expertise.
example for spooling: assume there are many computers and all of them want to print a data at a same time and give a print command on keyboard but there is only one printer between them. so printer will use the command to the first person who used to give at first according to the time but he will also accept the other persons command and keep them in a waiting state and when the print of 1st command is over it will automatically accept the another command for printing the data and acoording to this pattern only he will goes on and complete his task.... according to me spooling means this. further i cant say u.....

Not necessarily. It depends on what you are processing.
Spooling in Batch Poerating System utilise the CPU(prevents watage of time) as when no job batch remain to execute by CPU.Spooling is Simultaneous Peripheral Operation Online.
in off line spooling user has no interface with systems it strongly used in Batch system's.it mean's that you submit your request to system , system will cmputing and print result of request without interface with user.
Like a spool or a "print spooler", this suggests that spooling orders tasks in a linear fashion to be quickly executed in a sequential manner rather than multitasking several at once.

spooling stands for simultaneous peripheral operation on- line. it is a mechanism to deal with following issue:-a) to reduce the speed mismatch between slow input / output devices and CPU for better utilisation of the CPU.b) to convert manually exclusive I/O device into non mutually exclusive I/O devices so that they can be simultaneously used by multiple processes in multiprogramming system.

Dos files are the files with the extension .bat which are used for programming in DOS. This is also called as batch file programming.
Spooling
There is not switch called "if". We generally use "if" statement in batch programming in DOS.
Any turbo-charger that spins pressurised air into the cylinder makes a high pitched spooling sound is called a spooling turbo charger.
