Which of the following describes a DVD in terms of storage format?

A DVD, or Digital Versatile Disc, is an optical disc storage format that was developed to meet the growing demand for higher storage capacity than that provided by conventional Compact Discs (CDs). DVDs typically have significantly larger storage capabilities, allowing them to hold anywhere from 4.7 GB to 17 GB of data, depending on whether they are single-layer or dual-layer discs. This enhanced capacity enables DVDs to store not just audio and video files, but also software, games, and other digital content.

In contrast to the other choices, a DVD is not limited to audio playback; it is designed for a much wider range of multimedia uses. Additionally, it is certainly not an optical disc format with less capacity than a CD, as DVDs generally surpass CDs in storage capability. Furthermore, DVDs are distinct from digital tape formats, as they utilize a reflective optical surface for data storage, while tapes rely on magnetic storage technology. Thus, identifying a DVD as an optical disc storage format with higher capacity than a Compact Disc accurately reflects its purpose and capabilities in the realm of digital storage media.
