Today in class, we picked up our discussion from last Tuesday. Today's topic: expansion slots. Our discussion was about the five different types of expansion slots listed below.
PCI - is a computer bus for attaching hardware devices in a computer.
Accelerated Graphics Port (AGP) - is a high-speed point-to-point channel for attaching a video card to a computer’s motherboard's, primarily to assist in the acceleration of 3D computer graphics.
PCI Express (Peripheral Component Interconnect Express) (PCIe) - is a computer expansion card standard designed to replace the older PCI, PCI-X and AGP standards.
AMR (Audio/Modem Riser) - specification defines a hardware scalable OEM PC mother board riser card and interface, which supports both audio and modem functions. An MR slot will provide a Modem function, while an AMR slot will provide both an Audio and Modem function. The modem is a WinModem.
CNR (Communication and Networking Riser) - The Specification defines a hardware scalable Original Equipment Manufacturer (OEM) mother board riser and interface that supports the audio, modem, and local area network (LAN) interfaces of core logic chipsets.
Please note that Intel has two chipset and they the North Bridge and the South Bridge. The surprise of the day came when he took out some computers and had us in the class to dissemble the different components off the motherboard. Then remove the motherboard and re-install everything in its proper order.
Now I know how Dr. Frankenstein felt. “It’s Alive”!!!!
