Peripheral Component Interconnect (PCI)

PCI (Peripheral Component Interconnect) is considered a standard in a communication bus over which an extensive exchange of data takes place. The bus connects various peripheral hardware such as plug-in cards with the chip of the computer. The predecessor of Peripheral Component Interconnect was the ISA bus or Vesa local bus until the 1990s. The PCI bus allows connected plug-in cards to be automatically recognized and configured by the system. Plug-in cards include network cards, graphics cards or modem cards. Since the transfer speed became higher and higher over the years, PCI Express appeared in 2005, which replaced the normal PCI and enables higher transfer speeds.
