Question

Full form of DVD is ......

• A. Double value disc
• B. Double versatile disk
• C. Digital versatile disc
• D. None of these

Hint:

Always choose "Digital Versatile Disc" over "Digital Video Disc" in computer science exams, as it represents the official and generic capability of the storage medium.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question requires identifying the correct full-form expansion of the widely used computer hardware abbreviation "DVD".


Step 2: Detailed Explanation:
DVD is a highly popular optical disc storage format that was originally invented and developed in 1995.
The acronym officially stands for "Digital Versatile Disc".
In its early days, it was sometimes informally referred to as "Digital Video Disc" because its primary initial commercial use was for the distribution of movies. However, "Digital Versatile Disc" is the official and most technically accurate expansion since the medium is designed to be highly versatile—storing various types of data, including software applications, plain documents, and high-quality videos.


Step 3: Final Answer:
The full form of DVD is Digital versatile disc.

Answer 2

The question asks for the correct full form of the abbreviation DVD. Since DVD is an acronym, the wording of each option must actually match the letters D, V, and D in order. Let's test each option against this letter pattern.

1. Double value disc: This starts with "Double," which begins with the letter D, but the underlying term actually used for DVD is not "Double," it is "Digital." So this option is built on a mismatched first word and does not represent the real acronym.
2. Double versatile disk: This also opens with "Double" instead of "Digital," so even though "versatile" correctly supplies the V and "disk" attempts the second D, the first word is wrong. An acronym expansion has to match every letter exactly, and swapping "Digital" for "Double" breaks that match.
3. Digital versatile disc: Here, "Digital" supplies the first D, "versatile" supplies the V, and "disc" supplies the final D. Every word lines up exactly with the three letters of the abbreviation, and this is also the officially adopted expansion used in technical documentation.
4. None of these: Since one of the listed options already produces a letter-for-letter match with D-V-D, this choice cannot be correct.

Only "Digital versatile disc" reproduces the abbreviation's letters correctly, while the "Double..." options fail right at the first word.

Therefore, the correct answer is Digital versatile disc.
