1 Most popular bussystems Internal –ISA / EISA –VLB –PCI –AGP External –USB –Firewire

2 ISA (1980) (Industry Standard Architecture ) 8-bit bus 16-bit bus (compatible to 8-bit)

3 ISA (1980) (Industry Standard Architecture ) Graphiccards Controllercards (storage) Networkcards (MoDem, LAN) Soundcards Serial & parallel ports (com, lpt) Replaced in new systems (PCI-bus)

4 EISA (1988) (Extended Industry Standard Architecture ) Extension of ISA-Standart Bus-Mastering (direct communication between cards) Mainly used in Servers or network- hosts Compatible to ISA-Standart 32-bit EISA slot 16-bit ISA slot

5 Vesa-Local-Bus (VLB) (1992) (Video Electronics Standard Association) Compatible to ISA-standart 32-bit bus Mainly used for graphic- and videocards extension of the 486 processor/memory bus (only used in 486er systems) Not established due to PCI-system in connection with the Pentium-CPUs.

6 PCI (1993) (Peripheral Component Interconnect) Actual system standart 32 and 64 bit bus (with Bus- Mastering) First system controlled by the mainboards chipset Usable for nearly all device cards

7 AGP (1997) (Accelerated Graphics Port) 64 bit bus Used only for graphiccards different modes: –1xstandart –2xdouble data rate per clock –4xquad data rate per clock ability to share the main system memory with the video chipset

8 External Bus Systems USB 1.1 USB 2.0 Firewire 1 (i-link, IEEE 1394) Firewire 2

9 USB 1.1 / 2.0 (Universal Serial Bus) Hot plug Capability Hot swap (PNP) Built-in in all newer PCs Built-in Power supply Bandwith (max.): USB 1.1: 12Mbit / sec USB 2.0: 480Mbit / sec

10 Firewire 1 & 2 Hot plug capability Hot swap (PNP) Requires additional controller Built-in Power supply Bandwith (max.): Fw 1: 100 / 200 / 400 Mbit / sec Fw 2: up to 3,2 Gbit / sec Without power supply With power supply
