CD-ROM

CD-ROM


Compact disks can provide storage for around 650 Mbytes of computer data. This is roughly equivalent to 250,000 pages of A4 text. It is, therefore, hardly surprising that the compact disk has now become firmly established as a storage medium for a variety of different types of information, including text, drawings, sound and video (i.e. multimedia). The latest PCs offer CD-ROM drives that can be used to store data on recordable CDs (CD-R) or rewritable CDs (CD-RW). High-end PCs now also have DVD (Digital Versatile Disk).
