It uses a beam of light to "look" at the data. It starts the read on the inside of the CD.
Nope... the data on a DVD-ROM is packed much tighter. A CD-ROM cannot read DVD's but a DVD-ROM can read CD's
CD-Rw
A CD ROM is a standard compact disc containing data to be read by a digital device, such as a CD player or PC CD-ROM drive. A CD-R is a compact disc which data can be recorded, or burned (hence the term "burning cds). Usually, CD-R's are one shot deals meaning they can recorded until they are either filled up (usually 700 MB) or finalized. CD-R's whether filled up or not cant be read by a digital device until finalized.
Yepp.
A CDROM drive is neither an input device or an output device. A CDROM drive is a storage device.
The laser in the drive is the device that actually reads or writes data from and to the CD/CDRW/CDR.
A CD has a strip of information that is embedded within it. The information is stored on the strip on the CD. The lens from a radio reads the information for playback.
A small rig moves a laser along the CD, the laser reads binary data from the grooves in the CD and the drive's software interprets the results.
A CDROM is a disc that contains data and computer software like video gaming. Computers can read the CDROM it is a read only memory and cannot be written on.
CD's speed, size (amount of data it can hold) and the fact it is W.O.R.M., Write Once, Read Many vs W.M.R.M, Write Many, Read Many (Harddrive for example) are the major drawbacks for the CDRom as multimedia storage.
To mount a CD in SCO Open server UNIX: login as root make a directory named cdrom then # mount -f HS,lower /dev/cd0 /cdrom
Quite simply, a device that reads data CDs (such as those one install software from). CD drives can also be used to play music CDs.
