Which of the following is a type of software that stores an organized collection of data on a computer?

A database is a type of software specifically designed to store, manage, and organize large amounts of data on a computer. It allows users to create, retrieve, update, and delete data in a structured way, often through tables that can be related to one another. This organization enables efficient data management and querying, making it easier to perform complex searches and analyses.

In contrast, a spreadsheet is primarily used for calculations and data analysis through functions and formulas, but it does not inherently provide the same level of structured data organization as a database. A word processor focuses on text creation and editing, lacking the data management features found in a database. An operating system manages hardware and software resources on a computer but does not serve as a data store itself.

Given these distinctions, the database clearly fits the description of software that organizes and stores data effectively.
