In computing, an expansion card (also called an expansion board, adapter card, peripheral card or accessory card) is a printed circuit board that can be inserted into an electrical connector, or expansion slot (also referred to as a bus slot) on a computer's motherboard (see also backplane) to add functionality to a computer system. Sometimes ...
This is a partial list of expansion bus interfaces, or expansion card slots, for installation of expansion cards. Bus interfaces. Interface name Year introduced
A PCI-X Gigabit Ethernet expansion card with both 5 V and 3.3 V support notches, side B toward the camera. Typical PCI cards have either one or two key notches, depending on their signaling voltage. Cards requiring 3.3 volts have a notch 56.21 mm from the card backplate; those requiring 5 volts have a notch 104.41 mm from the backplate.
In addition to the seven standard expansion slots, the following computers contained additional, largely special-purpose expansion slots: Apple II and Apple II Plus: Slot 0 (50-pin, for the firmware card or the 16 kB Apple II Language Card) Apple IIe: Auxiliary Slot (60-pin; primarily for 80-column display and memory expansion)
ExpressCard, initially called NEWCARD, [1] is an interface to connect peripheral devices to a computer, usually a laptop computer.The ExpressCard technical standard specifies the design of slots built into the computer and of expansion cards to insert in the slots.
A PCIe card physically fits (and works correctly) in any slot that is at least as large as it is (e.g., a x1 sized card works in any sized slot); A slot of a large physical size (e.g., x16) can be wired electrically with fewer lanes (e.g., x1, x4, x8, or x12) as long as it provides the ground connections required by the larger physical slot size.
In servers, height for expansion cards is limited by rack units. A unit (U) is the traditional measurement used for server height. One server unit is equal to 1.75", 2U servers are 3.5", and so forth. Traditional 1U riser cards each fit 1 PCI slot, and 2U riser cards can fit 2 or 3 PCI slots, depending on whether they obstruct access to any PCI ...
CardBus slots are backwards compatible, but older slots are not forward compatible with CardBus cards. Although originally designed as a standard for memory- expansion cards for computer storage , the existence of a usable general standard for notebook peripherals led to the development of many kinds of devices including network cards , modems ...
