A PCI bus slot is a slot on a computer desktop machine that gives you expansion capabilities. When you buy a computer, you want to have a desktop machine that has at least two, if not three, extra PCI slots that will give you room for expansion. Later down the line, you can add another video card or a network card. Those are all PCI cards, and if you have extra expansion slots, you really give yourself room to grow down the line.
