NIMCET 2010 — Computer PYQ

Solution

In computer science, data is organized in a hierarchy where each level is composed of elements from the level beneath it. The correct logical order from the smallest unit to the largest is:

1. Character (Byte): A single letter, number, or symbol.

2. Field: A group of related characters (e.g., a "Name" or "Phone Number").

3. Record: A collection of related fields (e.g., all the information about one specific student).

4. File/Table: A collection of related records.

5. Database: The highest level, consisting of a collection of related files or tables.

Analyzing the Options:

• Option (a): Incorrect because a "Field" is larger than a "Character."

• Option (b): Incorrect because a "Record" is larger than a "Field."

• Option (c): Correct. It follows the logical progression: $Character\to Field\to Record\to Database$.

• Option (d): While it starts correctly ($Bit\to Byte$), it incorrectly places "Record" before "Field."

Correct Answer:

The correct option is (c).
