outputs are produced at once, usually at regular
intervals.

Batch processing
The data from customers is
collected together in a transaction
file. It is sorted in order of
customer number.
When the batch is processed, the
transaction file updates the
master file with the new meter
reading, calculates how much
energy was used and how much
to charge the customer.
Customer bills are produced and
sent out at the same time – this is
batch processing.

from an ATM.
