Payroll is often used as a good example when batch processing using magnetic tapes is considered appropriate. Why is payroll a good application for this type of storage device?

Payroll is a good application for batch processing using magnetic tapes because payroll data is typically processed in batches, such as at the end of each pay period or on a monthly basis. This data is also relatively simple and consistent, consisting of employee names, hours worked, and wages. Magnetic tapes are well-suited for batch processing because they allow for the efficient storage and retrieval of large amounts of data sequentially. Additionally, magnetic tapes are a cost-effective storage solution for payroll data, as they have a low cost per megabyte of storage compared to other storage devices. Overall, the use of magnetic tapes for batch processing of payroll data is a reliable, efficient, and cost-effective solution.
