What enables the computer to drive the speaker system?

The computer drives the speaker system through a combination of audio output hardware and software. The audio output hardware, such as a sound card or integrated audio chipset, converts digital audio signals into analog signals that speakers can reproduce. Additionally, audio drivers and software applications manage audio playback, allowing the computer to send the correct signals to the speakers based on the selected audio source. This integration enables seamless audio playback for various applications, from music to video.
