Why is direct accessing of data a big advantage over the sequential accessing of data?

Direct accessing of data offers significant advantages over sequential accessing, particularly by enabling fast, immediate access to specific data without the need to examine each record. This method allows for quick retrieval of information as it retrieves data directly from its storage location, rather than searching through all preceding records in a sequential manner.

This immediacy enhances efficiency, especially in applications where timely data retrieval is crucial. Users can retrieve the information they need instantly, which can significantly reduce the time spent on data processing tasks, especially when working with large datasets. In contrast, sequential access requires examining each record, which can be time-consuming and inefficient when dealing with vast amounts of data. Therefore, the ability to directly access data is a fundamental feature that improves operational performance in data management systems.
