What is a database primarily used for?

A database is primarily used for storing related data in a structured way that enables efficient information processing and retrieval. This core function allows users to manage large volumes of data systematically, ensure data integrity, and facilitate quick access and manipulation of the data as needed. Proper database management ensures that data is organized in a manner that supports various operations, including querying, reporting, and analysis.

While other options touch on important aspects of technology and cybersecurity, they do not align with the primary purpose of a database. Performing complex computational tasks typically falls under the realm of applications or programming environments rather than databases themselves. Encrypting sensitive information is a critical security measure for protecting data but is not the fundamental purpose of a database. Similarly, tracking network traffic and performance relates to network monitoring tools rather than the data storage functions of a database. Thus, the focus on storing and retrieving related data makes the correct choice the most relevant to the primary purpose of a database.
