CD DRIVE
In ordinary computer cd drives are used to acces data from CD.There are different types of CD Drives with diffent speeds are avilable.When shopping for a CD-RW drive. Look at the speeds on the box. This will look something like this: 2X / 4X / 32X. All numbers refer to how fast the drive compared to the speed at which a CD player reads a music CD (which is considered 1 times or "1X"). Data stored in CD may be of diffent formats.it may be either MP3,audio cd format etc.
CD Drive use compact disks, in fact, the same physical disk format as the ones we use for music.Special formatting is used to allow these disks to hold data. As CD-Drivess have come down in
price they have become almost as common in a new PC as the hard disk or floppy disk, and
they are now the method of choice for the distribution of software and data due to their
combination of high capacity and cheap and easy manufacturing. Recent advances in technology have
also improved their performance to levels approaching those of hard disks in many respects.
CD-ROM drives play a significant role in the following essential aspects of your computer system:
Software Support: The number one reason why a PC today basically must have a
CD-ROM drive is the large number of software titles that are only available on CD-ROM.
At one time there were a few titles that came on CD-ROM, and they generally came on floppy
disks as well. Today, not having a CD-ROM means losing out on a large segment of the PC
software market. Also, some CD-ROMs require a drive that meets certain minimum performance requirements.
Performance: Since so much software uses the CD-ROM drive today, the performance level
of the drive is important. It usually isn't as important as the performance of the hard drive or
system components such as the processor or system memory, but it is still important, depending on
what you use the drive for. Obviously, the more you use the CD-ROM, the more essential it is
that it perform well.
