Step-by-step explanation:
Point-of-sale terminals in store checkout lines sending sales data back immediately to a retailer's headquarters is an example of how information technology has improved concurrent control.
Concurrent control refers to the ability to monitor and make adjustments in real-time, ensuring that processes are running smoothly. In this case, the use of point-of-sale terminals allows retailers to have immediate access to sales data, enabling them to track inventory levels, analyze sales patterns, and make timely decisions.
For example, if a particular product is selling quickly, the retailer can order more to avoid stockouts. On the other hand, if a product is not selling well, they can adjust their marketing or pricing strategies. This real-time information helps retailers stay competitive and optimize their operations.
