COMPUTER FUNDAMENTALS

Detailed explanation-1: -An optical disk drive (ODD) uses a laser light to read data from or write data to an optical disc. These include CDs, DVDs, and Blu-ray discs. This allows you to play music or watch movies using pre-recorded discs.

Detailed explanation-2: -CD-R or CD-RW drives are also called CD writers, CD burners, or CD recorders can read the same formats as CD-ROM drives CD-DA, CD-ROM, and CD-R/RW discs but can also write data to inexpensive CD-R (write-once) and CD-RW (rewritable) discs.

Detailed explanation-3: -An optical disk drive uses a laser beam to read the data from the disk as it is spinning. It distinguishes between the pits and lands based on how the light reflects off the recording material. The drive uses the differences in reflectivity to determine the 0 and 1 bits that represent the data.

Detailed explanation-4: -Well-cared-for CDs can last many decades-even centuries. But storing a disc in a hot car or playing it often can eventually lead to “CD rot.” “By increasing the relative humidity and temperature, you’re increasing the rate of chemical reaction occurring, ‘’ she says.
