    8-bit bus

    16-bit bus (compatible to 8-bit)

  • EISA (1988)(Extended Industry Standard Architecture )Extension of ISA-StandartBus-Mastering (direct communication between cards)Mainly used in Servers or network-hostsCompatible to ISA-Standart32-bit EISA slot16-bit ISA slot

  • Vesa-Local-Bus (VLB) (1992)(Video Electronics Standard Association)Compatible to ISA-standart32-bit busMainly used for graphic- and videocardsextension of the 486 processor/memory bus (only used in 486er systems)Not established due to PCI-system in connection with the Pentium-CPUs.

  • PCI (1993) (Peripheral Component Interconnect)Actual system standart32 and 64 bit bus (with Bus-Mastering)First system controlled by the mainboards chipsetUsable for nearly all device cards

  • AGP (1997)(Accelerated Graphics Port) 64 bit busUsed only for graphiccardsdifferent modes:1xstandart2xdouble data rate per clock4xquad data rate per clockability to share the main system memory with the video chipset
