What is the purpose of the small cable connecting an IDE optical drive to the sound card?

To charge the optical drive
To send CD audio from the optical drive to the sound card
To synchronize audio playback
To connect the drive to the motherboard

The correct answer is: To send CD audio from the optical drive to the sound card

The small cable connecting an IDE optical drive to the sound card serves to send CD audio from the optical drive directly to the sound card. This connection, often referred to as an audio cable or CD audio cable, transmits the analog audio signals generated when a CD is played. By using this cable, the sound card can process and amplify these audio signals for output through speakers or headphones. While other components, such as the motherboard or power supply, are involved in the operation of the optical drive, their roles are not linked directly to the function of this specific cable. This connection is not intended for charging, synchronization of playback, or providing data to the motherboard, but rather for transferring audio output from the optical drive to the sound card, thereby allowing users to hear the audio content of CDs through their audio system.
