Compact Disc Read-only Memory, commonly known as a CD-ROM, is a data storage device. It is a pre-compressed optical disc that can contain data of multiple types including audio, video and other multimedia content. CD-ROMs remain popular although advancement in technology and introduction of DVDs have impacted their sales.

 

The invention of a CD-ROM has revolutionized the computing industry. Earlier, it was not possible to store large amount of data on a single medium. Floppy-discs were unable to store more than 1.44 MB of data. Standard CD-ROMs, on the other hand, can easily store up to 700 MB of data. Variants extend this capacity to as high as 900 MB. CD-ROMs are also used for storing audio and video content, which was not possible in floppy drives.

 

A CD-ROM works on a simple principle. It is data storage and retrieval device that can keep your data secure for decades. Read-only Memory constrains the disc’s ability to a single-time writing. This means that you cannot erase and write other data on a CD-ROM. The good thing is that there are many types of optical discs that come in rewritable format.

 

CD-ROMs are good for data that you want to secure for longer periods of time. It is thus good for text and spreadsheets, audio and video files. CD-ROMs were the first media that popularized movie distribution among a large section of people. VHS tapes were losing their popularity at that time and the omnipresence of computers had turned CD-ROMs into hot cakes. This is not the case any more given the advent of DVDs but average quality movies can still be stored on CD-ROMs.

 

The encouraging fact about CD-ROMs is that they have retained their significance. People and organizations still store data on CD-ROMs and they are still being used for distribution of video games, software and interactive content.
