what is cd rom
Pronounced see-dee-rom. Short for Compact Disc-Read-only Memory, a type of optical disk capable of shorting large amounts of data up to 1GB, although the most common size is 650 MB (megabyte). A single CDROM has the storage capacity to 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 comform 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 that support color, graphics, sound, and especially video and are well suitable for tutoring.
