Question: In general how much is the storage capacity of CD?

Answer:

In general, the storage capacity of a standard CD (Compact Disc) is approximately 700 megabytes (MB) of data. This capacity is based on the Red Book CD specifications, which are commonly used for audio CDs and CD-ROMs (read-only memory).

The 700 MB storage capacity is an approximate value because a small portion of the disc space is reserved for error correction and control information. This means that the actual usable space for storing data on a standard CD is slightly less than the total capacity.

It's worth noting that there are other types of CDs available, such as CD-R (recordable) and CD-RW (rewritable), which also have the same storage capacity of approximately 700 MB. These types of CDs allow users to write or burn data onto the disc using compatible CD writers or burners.
