What Is the Meaning of Disk and Disc?

- Disk: Typically used for magnetic storage like hard drives and floppy disks. For example, your computer’s hard disk stores all your files.
- Disc: Generally refers to optical storage such as CDs, DVDs, and Blu-ray discs. For instance, a CD disc can hold music or software.

Historical Background and Cultural Context
The terms disk and disc have evolved over decades. The word disk comes from the Greek “diskos,” meaning a flat circular object. In the 20th century, disk became the standard term for magnetic storage.
