A user has requested a DVD-ROM drive be added to their desktop PC so they can watch videos sent in by vendors. You only have a Blu-Ray player in inventory. Is it likely you deploy this to the user and meet their requirement?
The Blu-ray specification recommends but does not require backwards compatibility with DVDs. However in practice most Blu-Ray drives are backwards compatible with DVD discs and can play their content. You should check to be completely sure, but it is true that the likely scenario is your Blu-ray player will support DVDs.
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) The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games for the PlayStation 3, PlayStation 4, and Xbox One The name "Blu-ray" refers to the blue laser (which is actually a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs
