How can you visually tell the difference between different computer buses?
Usually the ISA is brown where as the PCI is white and AGP is purple. You can visually tell by the number of slots as well. The older ISA was always in great supply, but now it is outnumbered by the PCI. The ISA is most commonly found on the motherboards by a brown slot on the bottom of the board if you were to hold with the slots facing the back of the case. The PCI is usually shorter and in numerous quantities. The AGP will look sort of like a hybrid of the ISA and PCI, but it will have two slots. One in front, then a split and then a small one on the other side of it. The below web page has a good description and pics as well. http://www.just2good.co.uk/ioBusTypes.
