Question

NIMCET 2010 — Computer PYQ

NIMCET | Computer | 2010

Which of the following places the common data elements in order from smallest to largest?

Choose the correct answer:

Explanation

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:

Character (Byte): A single letter, number, or symbol.
Field: A group of related characters (e.g., a "Name" or "Phone Number").
Record: A collection of related fields (e.g., all the information about one specific student).
File/Table: A collection of related records.
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: $Character \rightarrow Field \rightarrow Record \rightarrow Database$ .
Option (d): While it starts correctly ( $Bit \rightarrow Byte$ ), it incorrectly places "Record" before "Field."

Correct Answer:

The correct option is (c).
