- DBMS: Database Management System (manages data)
- RAM: Random Access Memory (primary storage)
- CPU: Central Processing Unit (processor)

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question asks to identify the software system used for managing databases.

Step 3: Detailed Explanation:
* DBMS (Database Management System): A DBMS is a software system designed to store, retrieve, and manage data in a database. It provides an interface for users and applications to interact with the database, allowing for data definition, retrieval, update, and management. Examples include MySQL, PostgreSQL, Oracle, SQL Server.
* Operating System: An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. It manages the overall functioning of the computer, not specifically databases.
* Compiler: A compiler is a computer program that translates code written in one programming language (source language) into another language (target language), often machine code. It does not manage databases.
* Cache Memory: Cache memory is a small, high-speed type of computer memory that stores frequently used data or program instructions for rapid access. It is a hardware component that optimizes data access, not a database management system.
Therefore, DBMS is the correct term for managing databases.

Step 4: Final Answer:
DBMS is used to manage databases.
