An optical drive is an input and output device. It reads data from optical discs like CDs and DVDs (input) and writes data to these discs (output).
Some examples of optical disks include CDs (Compact Discs), DVDs (Digital Versatile Discs), and Blu-ray discs. These disks are used for storing and playing back various types of digital data such as music, videos, and software.

Optical discs are generally more reliable than floppy discs due to their resistance to environmental factors such as dust, moisture, and magnetic interference. Unlike floppy discs, which can degrade over time and are susceptible to physical damage, optical discs are designed for longevity and can store data safely for decades if kept properly. Additionally, the data on optical discs is encoded in a way that allows for error correction, further enhancing their reliability.
