Answer : 3. "Load the software into your computer "
Explanation :
While using a database management system, the first thing you have to do is install the software on your computer. Loading the software involves the installation process, which includes copying the necessary files and configuring the system to run the database management software effectively. Once installed, you can then create databases, define data structures, and start working with the DBMS to manage your data.

Answer : 3. "Data dictionary and transaction log "
Explanation :
During DBMS operation, essential files include the data dictionary, containing metadata like table structures, and the transaction log, recording all database transactions. The data dictionary guides the DBMS in understanding database organization, while the transaction log ensures data integrity by recording modifications. Both files are crucial for effective database management, enabling accurate querying, data manipulation, and system recovery in case of failures, ensuring the system's reliability and consistency.

Answer : 4. "hierarchical database"
Explanation :
In a hierarchical database model, a parent record type can be associated with one or more child record types, but a child record type can have only one parent. This hierarchical structure is represented as a tree-like schema, where each parent record can have multiple child records, but each child record has only one parent. This model is useful for representing data with hierarchical relationships, such as organizational structures or file systems.

Answer : 2. "RAM "
Explanation :
RAM (Random Access Memory) is an example of volatile memory. Volatile memory is a type of computer memory that requires power to maintain the stored information. When the computer is powered off or restarted, the data stored in RAM is erased. This is in contrast to non-volatile memory like hard drives or SSDs, where data is retained even when the power is turned off. Volatile memory, such as RAM, provides fast access to data for the computer's processor but does not retain data when the system is powered down.
