Which term is used for storing and retrieving data efficiently?

• A. Satellite
• B. Database
• C. Internet Telephony
• D. Network

Answer: (B)

The main idea here is how data is organized so it can be stored and accessed quickly. A database is an organized collection of data designed for efficient storage, management, and retrieval. It uses structures like tables and indexes and supports querying to find exactly the information you need fast, even as the data grows. Databases also handle data integrity, consistency, and concurrent access, which keeps information reliable when multiple people or programs read or write it at once. In contrast, a satellite, internet telephony, or a network describes storage in a very different sense, communication, or connectivity, rather than the structured, optimized data management that a database provides.
