The syllable ya at the end of the mantra denotes an offering. Thus the mantra Om Namah Sivaya actually means I offer to Siva a respectful invocation of His Name, and not merely I respectfully invoke His Name. Om Namah Shivaya mantra is sung by devotees in prayers and recited by yogis in meditation.
Short for Short for DVD-Recordable, a recordable DVD format similar to CD-R. A DVD-R can only record data once and then the data becomes permanent on the disc. The disc can not be recorded onto a second time. There also are two additional standards for DVD-R disks: DVD-RG for general use, and DVD-RA for authoring, which is used for mastering DVD video or data and is not typically available to the general public.
+RW and-RW: Rewritable discs that can be burned multiple times (up to 1,000 times for DVDs), allowing you to continually add more data. +RW is superior in quality to-RW. DVD-RAM: An optical, high-speed, rewritable disc that can store video with or without using a DVD burner. It's more robust than a traditional DVD, better protects data integrity, and can be rerecorded up to 100,000 times. DVD-RAM comes in two versions: a specially coated disc or a disc cartridge.
