Answer 1

Explanation:

Data are the principal resources of an organization. Data stored in computer systems form a hierarchy extending from a single bit to a database, the major record-keeping entity of a firm. Each higher rung of this hierarchy is organized from the components below it.

Data are logically organized into:

1. Bits (characters)

2. Fields

3. Records

4. Files

5. Databases
