ALSO CALLED: Peripheral Component Interconnect, Interconnections (of Electronic Components), PCI Buses, PCI
DEFINITION: PCI Express (PCIe or PCI-E) is a high-speed expansion card format thatconnects a computer with its attached peripherals. PCI Express wasdeveloped by Intel Corp. in 2004 to replace the peripheral componentinterconnect (PCI) and PCI-X expansion buses, along with the acceleratedgraphics port (AGP) graphics card interface. PCI-E allows data centermanagers to take advantage of networking technologies like  …

PCI BUS DEFINITION (continued): …  Gigabit Ethernet, RAID and Infiniband.PCI Express is a serial interface format, unlike PCI and PCI-X,which are parallel formats. Every device connected to a motherboardusing PCI-E has its own dedicated point-to-point connection. Each ofthese connections is called a "lane" and is controlled by a switch. As aresult of this architecture, connected devices don't have to sharebandwidth passing through a single bus, as they would using PCI. This inturn enables more scalable performance, lower latency and higher datatransfer rates. Condensing many parallel buses to one serial connectionsaves physical …
