CD-ROM

English (en)

CD-ROM
A CD-ROM (Compact Disc Read-Only 
Memory) is a type of compact disc 
that can only be read, not written 
to. It is a digital storage medium 
that can hold large amounts of 
data, including text, images and 
audiovisual.
Like a regular CD, a CD-ROM is read
by optical means. Unlike CDs, a 
computer can't record or change the 
information on a CD-ROM but can only 
access the information that has been 
prerecorded on it.
