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)

3. PCI-X Peripheral Component Interconnect extended History Products
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
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.

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 So WHY another Port?
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
