DBits, bytes, fields, files, records and databases

Correct answer: (B) Bits, bytes, fields, records, files and databases

Explanation

The data storage hierarchy runs bits, bytes, fields, records, files and databases.

Starting with bytes before bits reverses the two smallest units.

Placing records before fields breaks the correct order.

Placing files before records also breaks the order.

A field holds one data item, while a record groups related fields.

A database is an organised collection of related files.
