What is Batch Operating System ? Advantage and Disadvantage

What is Batch Operating System ?

• In Batch operating system, data is collected over a period of time and the processing of the data is deferred to a later time.
• This approach was used very commonly in the past when punch cards served as data storage media and is used as input into the computer system for processing.
• In batch processing, the data have first to be captured, normally as a form of source documents, like time cards, or alternatively, by RJE (Remote Job Entry) where data is gathered through remote terminals.
• The data will then be transmitted to the computer or the source document will be physically transported to the data centre where transcription (conversion of source document data into machine readable form) is performed.
• The data is processed by the computer and the resulting output is given to the users.
• Batch processing is suitable in application where there are large amounts of dataand when the turnaround times are not critical.
• As data are transcribed into machine readable form before submitting for processing, the speed of processing is therefore determined by the computer andnot by the operator.
• Payroll processing is suitable for batch processing as it is only performed on a regular basis. ( for example every month)

Batch Operating System Advantage:

• Less complicated.
• After input process is over, while processing is going on, user can attend other jobs.

Batch Operating System Disadvantage:

• Long turnaround time.
• Access to one is not possible.
• Difficult to provide priority scheduling.
• Not convenient for program development.
