What is the definition of Batch Processing?

Batch processing refers to the method of executing a series of jobs in a program on a computer without manual intervention. In this context, processes are collected or accumulated over time and then executed all at once, typically at a scheduled time. This approach is particularly efficient for tasks that do not require immediate processing, allowing for the handling of large volumes of data in a single operation.

The key characteristic of batch processing is that the data is not processed immediately as it is entered but is instead stored until a specified time when it is processed in bulk. This can lead to more efficient use of system resources, as the system can optimize the workload and manage resources effectively during the processing period.

In contrast, the other options describe different processing methods. For example, instant data entry aligns more with real-time processing, where actions are taken immediately as data is received. Real-time processing involves immediate processing of data, making it unsuitable for the definition of batch processing. Processing data by multiple systems simultaneously suggests a distributed system setup, which pertains to parallel processing rather than the batch approach.
