Answers
Answer:
Data storage is the recording of information in a storage medium.
1 Blu-ray disc. Blu-ray or Blu-ray Disc (BD) is a digital optical disc data storage format. It was designed to supersede the DVD format, and is capable of storing several hours of video in high-definition (HDTV 720p and 1080p) and ultra high-definition resolution (2160p).
2 CD-ROM disc. CD-ROM (Compact Disc, read-only-memory) is an adaptation of the CD that is designed to store computer data in the form of text and graphics, as well as hi-fi stereo sound.
3 CD-R and CD-RW disc. Stands for "Compact Disc Re-Writable." A CD-RW is a blank CD that can be written to by a CD burner. Unlike a CD-R (CD-Recordable), a CD-RW can be written to multiple times. The data burned on a CD-RW cannot be changed, but it can be erased.
4 DVD-R, DVD+R, DVD-RW, and DVD+RW disc.Essentially, each is a recordable variation of the DVD format. They allow the recording of audio, video, data, etc. on DVD discs. DVD-R is a one-time recordable disc, similar to a CD-R. If used to record video, it should be playable on most DVD players. DVD-RAM, DVD-RW and DVD+RW are competing, rewriteable DVD formats
