A motherboard has expansion slots, most boards even new ones will have a pci, pci-e 1.0, slots. Depending on how old the motherboard is it will not work well with todays software. The expansion slots today are mostly used for:
- Adding or replacing a video card if the orginial video port goes bad or not detailed enough (pixals in the image) to work with certain software.
- Adding USB ports if the if the older computer does not have enough or any. This way more modern perpherals (printers, keyboards, mouses, external hard-drives...etc.) can be used.
- Adding or replacing a network card.
Now take the newest boards, they have pci-e 2.0 16x, which are the fastest slots, but they still have a pci slot for say a wireless card.
Many of the connections for video, sound, keyboard, printer and anything else used on the computer is connected some way or another all built into the motherboard most times. Sometimes these connections go bad. Rather than buy another motherboard the expansion slots offers and alternative and possible upgrade to the repair of the problem.

A motherboard contains several integrated components. Most motherboards will contain: * An IDE controller * A SATA controller (on newer motherboards) * A floppy controller (on older motherboards) * RAM sockets * Expansion slot(s) * The BIOS chip * Power connector * Processor socket / slot * Serial ports (phased out on some newer motherboards) * Parallel ports (phased out on some newer motherboards) Many motherboards will also integrate components that can also be replaced by an add-in card: * Graphics chipset * Network controller * Sound card * USB connectors * FireWire connectors * Dial-up modem * eSATA connector
Yes, technology has changed quite a bit. Really old graphics card use PCI expansion slots, fortunately most motherboards still have PCI slots. Another expansion slot was invented called AGP (Accelerated Graphics port) used solely for graphics cards. This type of slot is rarely ever found on modern computers. Now graphics cards are installed into the PCI-Express x16 slot.
This would depend on the motherboard. I have seen older motherboards that were still trying to use IDE as a primary but had 2 or 3 SATA connections. Newer motherboards have primarily SATA connections.
PCIe (Peripheral Component Interconnect Express)
EBay works for me for the older cards, but newer cards are sold in all major retail outlets, like K-Mart, Target, etc.
No but you can find fairly nice video cards that fit into older expansion slots on ebay.
AnswerYes.Added:Sometimes! Not all AGP 1x or 2x video cards will have the same connection type as 4x or 8x cards, some older cards will not physically fit in the slot for modern motherboards.
No, they cannot.
Its AMR Audio/Modem/Riser Card.
The newer cards don't work on older computers, but the way the older ones work are similar. The older ones just are not as fast, don't have anywhere as much memory, and don't have as much features. They didn't have as much acceleration and processing, so the drivers (and thus CPU) had to do more of the work. Of the older stuff, the monochrome cards were among the fastest. They were simpler than the color cards and did less, so they were faster. For PCs, there were first the 8-bit ISA cards, then the 16-bit ISA cards, then the VLB cards, then PCI, then AGP, then PCIe. Of course, all along that line of development, there were always motherboards which incorporated the video card as part of it. On one hand, that should be slightly faster that way, but they had limited features, and if they went bad or you wanted to upgrade, you were stuck.
