(March 2013) () Batch processing is the execution of a series of jobs in a on a without manual intervention (). Strictly speaking, it is a: the execution of a series of programs each on a set or 'batch' of inputs, rather than a single input (which would instead be a custom ).

Contents • • • • • • • • • • • • • Benefits [ ] Batch processing has these benefits: • It can shift the time of job processing to when the computing resources are less busy. • It avoids idling the computing resources with minute-by-minute manual intervention and supervision. • By keeping high overall rate of utilization, it the computer, especially an expensive one.

• It allows the system to use different for interactive and non-interactive work. J.a.

It also has multiple disadvantages, for instance users are unable to terminate a process during execution, and have to wait until execution completes. History [ ] The term 'batch processing' originates in the traditional classification of as (one-off production), (production of a 'batch' of multiple items at once, one stage at a time), and (mass production, all stages in process at once). Early history (19th century through 1960s) [ ].

IBM Type 285 tabulators (1936) being used for batch processing of punch cards (in stack on each machine) with human operators at U.S. Social Security Administration Batch processing dates to the late 19th century, in the processing of data stored on decks of by, specifically the by, used for the. This was the earliest use of a machine-readable medium for data, rather than for control (as in; today control corresponds to code), and thus the earliest processing of machine-read data was batch processing. Each card stored a separate of data with different fields: cards were processed by the machine one by one, all in the same way, as a batch. Batch processing continued to be the dominant processing mode on from the earliest days of electronic computing in the 1950s. Originally machines only tabulated data, counting records with certain properties, like 'male' or 'female'. In later use, separate stages or 'cycles' of processing could be done, analogous to the stages in batch production.

In modern data processing terms, one can think of each stage as an clause, such as SELECT (filter columns), then WHERE (filter cards, or 'rows'), etc. The earliest machines were built (hard-wired) for a single function, while from 1906 they could be rewired via, and electronic computers could be reprogrammed without being rewired. Thus early multi-stage processing required separate machines for each stage, or rewiring a single machine after each stage. Early electronic computers were not capable of having multiple programs loaded into main memory (), and thus while they could process multiple stages on a single machine without rewiring, the program for each stage had to be loaded into memory, run over the entire batch, and then the program for the next loaded and run. There were a variety of reasons why batch processing dominated early computing.
