in A+
I noticed that in the objectives for the Core exam you must know what a Riser card is. Can anyone tell me what is the purpose for this card and how it would relate to the exam??

Thanks a lot

    On some of the smaller cases (Compaq specficially), there was not enough physical room inside for expansion cards, they were simply too narrow.
    A single expansion board, or daughter board, was placed perpendicular to the motherboard, and expansion cards plugged in that:

    Riser card is an expansion card that fits a PCI slot(or even ISA I guess)
    which adds more expansion slots, eg., if you only have one PCI slot left on your MB, you can put in a riser card and add 2 or 3 more slots for additional expansion cards.

    AMR: the Audio Modem Riser specification was developed by Intel to eliminate legacy support for audio and modem functions on motherboards. This specification allows for designs without I/O operations for the riser card or daughterboard. The slot is brown in color and has the dimensions of 1 13/16 inches in length by ¾ inches wide. This expansion slot is not commonly seen as newer technology is moving away from modems to broadband communications.


    CNR: the Communications Network Riser is similar to the AMR. The specification provides interfaces to support multi-channel audio, V.90 analog modem, telephone line-based home networking, 10/100 Ethernet-based networking, as well as expandability for future technologies.

    Riser card: expansion slots that are mounted on a bus riser card that plugs into the motherboard. In most designs, expansion cards plug sideways into the riser card. It works on LPX, ATX and NLX form factors

    There are three flavors I guess ISA, 32 and 64 bit PCI, so with it you can have more expansion slots
