What is PCI?
PCI - Peripheral Component Interconnect" - refers to a standard communication bus for connecting peripheral devices to a central computer.
Certain plug-in cards can be automatically recognized and configured via PCI bus. The computer system can therefore be expanded with network cards such as sound, graphics or modem cards, etc., both in terms of performance and the number of functions.
The PCI as an interface standard was introduced in the early 90's and became obsolete around 2000, because the transfer speeds were no longer sufficient, because the plug-in cards had to share the available bandwidth. You can find our selection of PCI cards here:
What is PCIe?
The PCI system was replaced by PCI Express with higher data transfer and clock rates from 2004. This was made possible by dedicated point-to-point connections, which are serial self-clocked connections. This is fast and secure and provides full bandwidth to each plug-in card. This makes PCIe technology particularly suitable for demanding graphics cards.
And last but not least PXI?
The highest bandwidth with the lowest runtime is currently offered by the PXI standard, PCI eXtensions for Instrumentation. PXI is a special update of the CompactPCI standard for instrumentation and thus also serves the metrological necessities such as cooling, quality of the supply voltage or mechanical properties. A detailed description of this technical solution can be found on our LXinstruments page on PXI technology.
