Question

The process of comparing input data with some known data is known as:

• A. Data Validation
• B. Storage data
• C. Data entry
• D. Redundant data

Hint:

Data validation compares input data with some known data to check that it is correct.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
When data is entered in software, the software should check it.
The question gives the meaning and asks for the term.

Step 2: Working Out the Answer:
Data validation is the process of comparing input data with some known data.
For example, the software checks a date or a ledger name against what is allowed. This catches wrong entries.
So the answer is Data Validation, option (A).

Step 3: Why the Other Options Are Wrong:
Option (B): Storage data is data kept in a file or database. It is not a process of comparing.
Option (C): Data entry is the act of typing data into the system. It is not a comparison.
Option (D): Redundant data is data that is repeated needlessly. It is not a process either.

Final Answer:
The process is called Data Validation. This is option (A).
