Final answer:
Computers are necessary for automatic processing tasks to manage and execute routine tasks, handle large data sets, and perform complex data management efficiently and accurately.
Step-by-step explanation:
Computers are necessary for automatic processing tasks because these tasks generally measure efficiency and accuracy in data management. When we refer to automatic processing, we are discussing the unconscious encoding of information such as time, space, frequency, and word meanings, things that we can recall effortlessly. However, computers excel in another kind of automatic processing: the ability to perform routine tasks quickly and cost-effectively, replacing manual human labor in areas such as bookkeeping, clerical work, and repetitive tasks on production lines.
For instance, in supermarkets, automated self-scan checkouts are an example of how one employee can oversee multiple transactions at once, which previously would have required one cashier per checkout. This level of automation and data processing is only possible with the use of computers that can store and execute calculations on large data sets. Moreover, computers have transformed the organization and processing of information across various fields, making them indispensable for many professional and academic activities, such as research and complex data management tasks.
