The PCI and PCIe cards are available in standard and low profile installations to expand your system's use. While ExpressCards can provide the same resources, its format is different because it can only work in a 34mm card slot of a laptop computers, the PCMCIA and PCI card's interface can offer cable type connections for multiple serial port operation.
