  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: • 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

  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 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

  11. Thanks for listening • Feel free to ask questions
