You can connect an audio card or a modem card to an audio/modem riser (AMR) slot.
normally the PCIE slot
The slot which the video card needs to work. The slot is usually either an AGP slot (which is currently outdated), or the more recent PCI-E slot, which all new graphics cards nowadays use.
yes
A video card is plugged into an expansion slot on the peripheral bus. The exact type of peripheral bus slot varies according to the type of motherboard used. Originally, video cards were plugged into an ISA slot. Eventually they went in PCI slots, then AGP slots, and today, PCI-Express slots. Regardless of the type of peripheral bus interface, the peripheral bus connects peripheral cards, also called expansion boards, with the system chipset.
An AGP slot is a post-PCI/pre-PCIx graphic card interface bus. It was a step up from the PCI video cards, but were phased out with the PCIx standard.
"AMRStands for (Audio/Modem Raiser) Which is used to convert analog audio to digital audio the card is said to be raiser because it raises the audio"Edit: That is incorrect. AMR stands for "Audio/Modem Riser". The AMR slot's purpose was similar to that of the, then standard, ISA slots, but specifically designed to accommodate smaller, inexpensive modem riser cards, audio riser cards and network riser cards. Intel introduced them on September 1998 as a way to reduce the total cost of computer systems by dividing the logic between the riser cards and their respective controllers on the motherboards.Later, Intel replaced AMR slots with CNR (communication and networking riser) slots. Though the two are similar, they slightly differ structurally and CNR cards also differed in two other areas: CNR supported Plug & Play cards and they offered the option to be either software based (via the CPU) or controlled by hardware acceleration (dedicated ASIC). To my knowledge though, riser cards that work in AMR slots also work in CNR slots. Neither slot gained popular acceptance by users, either initially or in time. This was likely because the riser cards relied on the CPU to handle alot of their workload, noticably slowing it down. So that's probably why you won't find AMR-compatible cards anywhere today. In 2000, ACR (Advanced Communications Riser) slots replaced both AMR and CNR, but ultimately integrated components made all three slots obselete.Sources:Wikipedia.orgAndrews, Jean. A+ Guide to Managing and Maintaining Your PC, 7th edition.Boston, MA: Cengage Learning, 2010. Print.Note:Nothing is "raised" (as suggested earlier by another user). The reason AMR slots accommodated audio cards is likely because it was it was a low priority component (in terms of the bus traffic going to the south bridge and CPU). Regardless of this, analog to digital audio conversions occur on integrated circuits on the sound card and doesn't raise the volume or any other aspect of the audio data (or data on modem/network cards for that matter).
pci bus
Several hundred video cards, based on dozens of chipsets, support the AGP bus.
Some of the higher end cards will use a double-slot format, where the card takes of two of the rear slots on the motherboard. You can then use two screws to support the card. The PCI-E bus also has a retention clip on the slot that locks the card into place. Remember to release the clip when you take the card out!
PCI
No. Only one card will fit in the slot at one time. SOME type 1 cards will work in type 2 slots, but it is best not to do that. You can damage the motherboard by using the wrong type card in a slot.
A specification for extending the internal circuitry bus that transmits data from one part of a computer to another by inserting circuit boards. It allows the expansion of a computer by inserting printed circuit boards, or expansion boards, into sockets expansion slots inside the PCI bus. Full form: peripheral component interconnect.
