Peripheral Component Interconnect
(PCI) Technology
The Power Macintosh 4400 offers peripheral component
interconnect (PCI) expansion. Because the PCI bus is an
industry standard, most existing PCI 2.0-compliant cards
(with the addition of a Macintosh OS-specific software
driver) will work in these computers.
PCI offers significantly higher performance than the NuBus
architecture used in previous Macintosh models. Running at
33 MHz, the PCI bus is up to three times faster than NuBus,
offering overall enhanced system performance, particularly
in the areas of video and networking.
PCI expansion cards are mounted horizontally in an adapter
card.
