- compact disc read-only memorysearch for term
A computer storage medium which can store large amounts of information; generally used to distribute software or multi-media for use on computers with CD-ROM drives. CD-ROM disks look just like music CDs and cannot be altered by a user. Most CD-ROMs can store 650 megabytes of data.A single CD-ROM has the storage capacity of 700 floppy disks, enough memory to store about 300,000 text pages. CD-ROMs are stamped by the vendor, and once stamped, they cannot be erased and filled with new data. To read a CD, you need a CD-ROM player. All CD-ROMs conform to a standard size and format, so you can load any type of CD-ROM into any CD-ROM player. In addition, CD-ROM players are capable of playing audio CDs, which share the same technology. CD-ROMs are particularly well-suited to information that requires large storage capacity. This includes large software applications, graphics, sound, and especially video.
