Presentation transcript:

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

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

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

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

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.

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

AGP (1997) (Accelerated Graphics Port) 64 bit bus Used only for graphiccards different modes: 1x standart 2x double data rate per clock 4x quad data rate per clock ability to share the main system memory with the video chipset

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

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

Firewire 1 & 2 Hot plug capability Hot swap (PNP) Without power supply With power supply 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
