Tech Lowdown – PCI Express–The Next Generation Bus for the PC
 PCI Express is designed as a high-speed upgrade for the 32-bit parallel PCI bus. The PCI Express interface is a bi-directional serial connection that transports data in packets similar to the method used for Ethernet connections. Each point-to-point serial connection, or “lane”, utilizes two pairs of differential data lines. For devices like video cards that require significant data transfer, up to 32 lanes can be stacked together to increase the amount of bandwidth available. The PCI Express x1 (single lane) connector is capable of bidirectional data transfers up to 250MB/s, which can easily handle even sixteen of the fastest high-speed serial ports.
