Final answer:
Larger file sizes in databases are disadvantageous because they consume more storage space, potentially slowing down database operations and increasing costs. Option C is correct.
Step-by-step explanation:
The question addresses how larger file size can be a disadvantage in a database environment. The correct answer is c) Larger files consume more storage. This is because large files take up substantial space on data storage devices, which both increases cost and can potentially slow down database operations due to longer access times and data transfer speeds.
In contrast to the other options, large data files could negatively impact the performance by requiring more system resources for their processing and maintenance, therefore, unlike option a, it does not improve performance. Also, larger files do not necessarily enhance data retrieval as suggested in option d; in fact, they can hamper it. Option b is incorrect as file size directly impacts various aspects of database management.
In a database environment, file size can be a disadvantage because larger files consume more storage. When files are larger, they require more disk space to store the data, which can lead to increased costs for purchasing and maintaining storage devices. Additionally, larger files can also impact performance since it takes more time and resources to read and write larger files.
