Final answer:
The DBMS process that stores data is called the data storage or database engine component. It ensures efficient organization and security of the data on a physical storage medium.
Step-by-step explanation:
The DBMS (Database Management System) process that stores data is known as the data storage or database engine component. This core function of the DBMS takes the data provided by the users or applications and stores it on a physical medium, such as a hard drive or SSD. The DBMS ensures that the data is organized efficiently for quick retrieval and is securely stored so that it is protected from unauthorized access or corruption. The data storage process is vital, as it enables the persistent storage of data so that it can be used later, even after the application that created it has stopped running.
