What does a 74-minute CD capacity represent in bytes?

A 74-minute CD holds about 783,216,000 bytes of raw audio data and roughly 650 MB of file storage when formatted as a data disc.

How is a gigabyte (10^9 bytes) different from a gibibyte?

A gigabyte (10^9 bytes) uses the decimal SI prefix and equals one billion bytes, whereas a gibibyte (GiB) is a binary unit equal to 2^30 bytes.

Why convert CD capacity to gigabytes (10^9 bytes)?

Converting enables better comparison and compatibility between legacy CD storage sizes and modern digital storage measurements.
