Final answer:
Automation decreases manual entry and increases accuracy in various tasks, such as self-scan checkout aisles in supermarkets.
Step-by-step explanation:
The use of automation decreases manual entry and increases accuracy. Computers can be programmed to perform routine tasks faster and more efficiently than humans, reducing the need for manual input and minimizing the chances of errors. For example, in a supermarket, self-scan checkout aisles with automated cashiers replace the need for multiple paid employees, allowing one cashier to oversee transactions at several aisles.
