Document Summary

Subsystem consisting of speakers and a sound card. Attach to the motherboard and enable your computer to produce sounds. Most computers ship with a basic sound card, most of which are 3d sound cards. 3d sound is better at convincing the human ear that sound is omni-directional meaning that you cannot tell from which direction the sound is coming: produces a fuller, richer sound than a stereo. How video is displayed depends on two components: video card, monitor. A video card is an expansion card that is installed inside your system unit to translate binary data into the images you view on your monitor. Modern video cards include ports allowing you to connect different equipment as well as their own ram, this is called video memory. Videos come with their own processors calls to the cpu for graphics processing and are redirected to the processor on the video card.
