Digital Versatile Disk

Dynamic Video Disk

Digital Video Disk

Correct Answer : Digital Versatile Disk

Stands for "Digital Versatile Disc." A DVD is a type of optical media used for storing digital data. It is the same size as a CD, but has a larger storage capacity. Some DVDs are formatted specifically for video playback, while others may contain different types of data, such as software programs and computer files.

The original "DVD-Video" format was standardized in 1995 by consortium of electronics companies, including Sony, Panasonic, Toshiba, and Philips. It provided a number of improvements over analog VHS tapes, including higher quality video, widescreen aspect ratios, custom menus, and chapter markers, which allow you to jump to different sections within a video. DVDs can also be watched repeatedly without reducing the quality of the video and of course they don't need to be rewound. A standard video DVD can store 4.7 GB of data, which is enough to hold over 2 hours of video in 720p resolution, using MPEG-2 compression.

Expansion of RDBMS is

Relational Database Memory System

Recurring Database Memory System

Relational Database Management System

Repairable Database Management System

Correct Answer : Relational Database Management System

A relational database management system (RDBMS) is a database management system (DBMS) that is based on the relational model as introduced by E. F. Codd, of IBM’s San Jose Research Laboratory.

A relational database management system (RDBMS) is a collection of programs and capabilities that enable IT teams and others to create, update, administer and otherwise interact with a relational database. RDBMSes store data in the form of tables, with most commercial relational database management systems using Structured Query Language (SQL) to access the database. However, since SQL was invented after the initial development of the relational model, it is not necessary for RDBMS use.

The RDBMS is the most popular database system among organizations across the world. It provides a dependable method of storing and retrieving large amounts of data while offering a combination of system performance and ease of implementation.
