Presentation Transcript

  1. PCI

  2. Peripheral Component Interconnect • History • Created by Intel to replace the IBM's MCA. • Created for standardization • PCI Ports • Video Card (legacy or hard to find) • Sound Card • USB hubs • NIC • Disk controllers (IDE) http://www.barc.gov.in/technologies/images/pc_mca_if.jpg

  3. PCI-X • Peripheral Component Interconnect extended • History • Developed by IBM, Compaq/HP. • PCI-X only found in servers • Overcome limitations of PCI • Introduction of faster products • Products • Raid Controllers • Fiber & Gigabit Ethernet

  4. North Bridge & South Bridge • South Bridge • Communicates and handles all the information received from your components. • North Bridge • Handles communication from RAM (depends on manufacture) to the CPU • Handles communication from the South Bridge to the CPU. • Think of them like secretaries to the CPU. http://static.ddmcdn.com/gif/motherboard-bridges-diagram.jpg

  5. AGP • Accelerated Graphics Port • History • Created by Intel • Interface made for Graphics • No longer used (legacy)

  6. PCI VS AGP • Why AGP when you have PCI? • PCI can’t handle the Graphical Demand • Integrated GPU into North Bridge • Faster speeds.

  7. PCI express • History • Created by Intel, Dell, HP, and IBM • So WHY another Port? • Design improvements • Made to handle any component • Replacement for AGP and PCI

  8. PCI express versions • x1x4x8x16 • They are forward compatible with each other. • Allows for high-end & low end card • Also helps manufacture
