Final answer:
Decentralized processing is the scenario where each department has its own computer for processing tasks, leading to independent operation and potentially increased efficiency.
Step-by-step explanation:
In decentralized processing, each department has its own computer for performing processing tasks. This contrasts with centralized processing, where a single mainframe or data center handles the processing for the entire organization. Decentralized processing allows departments to work independently on their tasks, which can lead to enhanced efficiency and faster decision-making.
