Final answer:
The advent of personal computers has led to the decentralization of data processing activities and an increased concern over the accuracy of computerized processing.
Step-by-step explanation:
The advent of personal computers has resulted in a decentralization of data processing activities. Previously, computer technology was largely confined to universities and the military, but the introduction of affordable personal computers made computing more widely accessible. As a result, individuals now have the ability to process and store data on their own devices, reducing the reliance on centralized data processing systems. Furthermore, the availability of personal computers has also led to an increase in concern over the accuracy of computerized processing. With more individuals relying on computers for various tasks, it is important to ensure the accuracy of computerized data and processes to prevent errors and misinformation. In summary, the advent of personal computers has decentralized data processing activities and increased concern over accuracy of computerized processing.
