Which statement describes a batch processing system?

• A. A group of transactions that are accumulated, then processed all at one time
• B. The disadvantage to batch processing is TIME
• C. It processes transactions immediately as they occur
• D. It stores data for later processing

Answer: (A)

Batch processing groups transactions into a batch and processes them together in one run. This approach collects data over a period and then runs the processing all at once, often on a scheduled basis, which improves efficiency and throughput by minimizing per-transaction overhead. It’s different from real-time processing, which handles each transaction immediately as it occurs, and from simply storing data for later processing, which describes an accumulation but not the characteristic that processing happens in a single consolidated operation. The statement about accumulating transactions and then processing them at once best captures what batch processing is.
