Discs (or disks) are flat, circular objects that can be made from various materials, such as plastic, metal, or glass. They are commonly used for storing data, like in the case of CDs and DVDs, which hold music, videos, and software. Discs can also refer to physical items like frisbees or hockey pucks, which are designed for recreational activities. In technology, discs are often used in computers and gaming consoles for reading and writing data. Hard disk drives (HDDs) use spinning discs to store information magnetically, while solid-state drives (SSDs) use flash memory for faster access. Discs play a crucial role in both entertainment and data storage.
