High Quality Content by WIKIPEDIA articles! In mainframe operating systems, when a job is submitted, the operating system takes the job through a series of steps known as the job processing cycle. A large number of jobs is usually executed in a given time period, such as night, which is a scheme historically known as batch processing. Regardless of the job stream that a given job will follow, its processing cycle always contains the same sequence of steps: the steps involved in the job processing cycle include: sourceing of the data, arranging the sourced data in order to avoid erratic or typographic error, inputing the arranged data into the computer for processing, outputing of the processed data inform of information, and lastly is the transmission of the information to where it will be useful. this transmitted information can also serve as a source data for further processing that is why it is called the job processing cycle.
