Which hardware device uses lasers to interact with CDs and DVDs?

The hardware device that uses lasers to interact with CDs and DVDs is the optical drive. Optical drives are designed to read and write data from optical discs, which include CDs, DVDs, and Blu-ray discs. The mechanism within an optical drive employs lasers to read the encoded data on these discs. When a disc is inserted, the drive spins the disc while a laser beam is directed onto the surface of the disc to detect the pits and lands that represent the data. This process is essential for playing music, watching movies, or accessing files stored on these media.

In contrast, the other options focus on entirely different functionalities. An SD card slot is used for reading data from SD memory cards, a USB 2.0 port serves to connect various peripherals for data transfer, and a Bluetooth device facilitates wireless communication between devices. Each of these serves a specific purpose unrelated to the optical reading or writing process involved in handling CDs and DVDs.
