What is the role of an optical drive?

The role of an optical drive is to read and write data on discs such as CDs, DVDs, or Blu-ray discs using laser technology. This process involves focusing a laser beam onto the disc surface, where the data is encoded in the form of pits and lands (reflections), allowing the drive to access and manipulate that information. Optical drives are commonly used for various tasks such as installing software, playing media, or backing up files.

Other options, while related to aspects of computing, do not align with the specific function of an optical drive. Enhancing system performance, providing hardware encryption, or storing data in cloud services involve different components or technologies that serve distinct purposes within a computer system. Therefore, the primary and definitive purpose of an optical drive is its capability to read and write discs using lasers or light.
