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 topic is Computer Terminology and Abbreviations. The question seeks the correct expansion of the acronym "DVD". This is a common point of confusion because the term has evolved since its inception in the mid-1990s. Understanding the official terminology is important for technical accuracy in the field of information technology and digital media.
Step 2: Key Formulas and approach:
Since this is a nomenclature-based question, the approach involves identifying the official designation provided by the DVD Forum (the international body that defines DVD standards). We evaluate the adjectives "Digital," "Versatile," and "Video" to see which combination represents the official technical name of the medium as a general-purpose storage device.
Step 3: Detailed Explanation:

When the DVD was first introduced in 1995, many people referred to it as a "Digital Video Disc" because its primary use was replacing VHS tapes for movies.

However, as the technology was adopted by the computer industry for software and data storage, the "Video" description became too narrow.

The manufacturers and the DVD Forum officially decided that the technology was "Versatile" because it could hold any type of data, not just video files.

Thus, "Digital Versatile Disc" became the official and correct full form.

Options like "Double value disc" or "Double versatile disk" are incorrect fabrications and do not exist in technical literature.

Step 4: Final Answer:
The full form of DVD is Digital versatile disc.

Answer 2

Beyond expanding the letters D, V, and D, checking the exact terminology used in each option helps rule out the wrong choices, since optical storage devices and magnetic storage devices use different spellings for very similar sounding words.

1. Double value disc: "Double" is never the term used to describe DVD's capacity or type, and "value" is not a technical property used in naming storage media. This combination doesn't correspond to any established term.
2. Double versatile disk: Optical storage media such as CDs, DVDs, and Blu-ray media are conventionally spelled "disc" with a c, while "disk" with a k is reserved for magnetic storage devices such as floppy disks and hard disks. Since a DVD is an optical medium, ending its name in "disk" is inconsistent with standard terminology, and it also repeats the incorrect "Double" opening.
3. Digital versatile disc: This uses the correct optical-media spelling "disc," and each word accurately reflects the technology: "Digital" describes how the data is encoded, and "versatile" describes its ability to store many types of content beyond video.
4. None of these: Not applicable, since a technically consistent and correctly spelled option is present among the choices.

Checking both the accuracy of each word and the correct optical-media spelling convention confirms that only one option holds up.

Therefore, the correct answer is Digital versatile disc.
