A CD-ROM which stands for a Compact Disc Read-Only Memory, uses the same technology as a CD, it is laser read (although it has been said to sometimes be optically ready)data warehousing device, which means that text, imagery, audio and video can be stored on these discs. A CD-ROM is a medium for the use of storage of huge amounts of information, this then can be accessed through the CD-ROM drive on a computer.
One CD-ROM can store 650-900 megabytes of data. The length of time that this data may be accessible on the CD-ROM is debatable, this all depends on the real quality of manufacturing, it has been estimated to last around 2-15 years. CD-ROM databases that have sound effects already stored on them in a library are the most popular type of CD-ROM'S, these are called Ambient rom database's, may databases are available to buy that you can then store on your choice of library storage, if you would only need to use it once and not again you can hire these from a library.
