What is a common use of an optical drive?

An optical drive is primarily used for reading or writing data on optical discs, which include CDs, DVDs, and Blu-ray discs. This technology utilizes laser light to access and store data on these discs. Optical drives are commonly found in computers to allow users to install software, play media, or perform backups by writing data onto discs.

The option highlighting the function of reading or writing to CDs and DVDs accurately reflects the core purpose of an optical drive. Users often rely on these capabilities for various tasks such as playing music CDs, watching movies on DVD, or burning data onto discs for storage or sharing purposes. Understanding this function is essential for recognizing how optical drives fit into both data management and entertainment systems.
