CD ROM INFORMATION

CD ROM INFORMATION 


A CD-ROM, short for Compact Disc Read-Only Memory, is a type of optical storage medium widely used in the past for data storage. It consists of a polycarbonate disc with a reflective surface, which is capable of storing digital information in the form of pits and lands. The disc's read-only nature means that data can be read from it but not written or modified.
Typically, a standard CD-ROM can store up to 700 MB of data, equivalent to about 80 minutes of audio or various types of files, such as software, documents, images, and videos. These discs became popular in the 1990s and early 2000s as a means of distributing software and multimedia content.
To read the data stored on a CD-ROM, a laser beam is used to detect the patterns of pits and lands, and this information is then translated into digital data that can be accessed by a computer or CD-ROM drive. While CD-ROMs have been largely replaced by more advanced storage technologies such as DVDs and USB flash drives, they remain an essential part of computing history, playing a significant role in the development of digital data storage and distribution.
