As mentioned above in the how bono y mary j blige one many expansion slots does my computer have, every motherboard is different, and the only way to determine the type of expansion slots on the motherboard is through the motherboard manual or by opening the computer case and visually examine.
This may have been electrically comparable to the XT bus; it most certainly had some similarities since both essentially exposed the 8088 CPU's address and data buses, with some buffering and latching, the addition of interrupts and DMA provided by Intel add-on chips, and.Expansion cards allowed a processor system to be adapted to the needs of the user, allowing variations in the type of devices connected, additions to memory, or optional features to the central processor (such as a floating point unit ).Many of these computers were also passive backplane designs, where all elements of the computer, (processor, memory, and I/O) plugged into a card cage which passively distributed signals and power between the cards.The original PC Card expansion card standard is essentially a compact version of the ISA bus.You're most likely only going to encounter AGP, PCI, and PCI Express when working with computers today.
Your RAM must be compatible with your system or your system just won't work.
1, contents, history edit, main article: Bus (computing) History, even vacuum-tube based computers had modular construction, but individual functions for peripheral devices filled a cabinet, not just a printed circuit board.

In 2004, implements the logical PCI protocol over a serial communication interface.
PCI - Network card, scsi, Sound card, Video card.
Some cards are "low-profile" cards, meaning that they are shorter than standard cards and will fit in a lower height computer chassis.Since reliable multi-pin connectors are relatively costly, some mass-market systems such as home computers had no expansion slots and instead used a card- edge connector at the edge of the main board, putting the costly matching socket into the cost of the peripheral device.Apple used a proprietary system with seven 50-pin-slots for Apple II peripheral cards, then later used the NuBus for its Macintosh series until 1995, when they switched to a PCI Bus.Some of these standadards were VMEbus, STD Bus, and others.CT915218, dDR2 PC2-6400 CL6 Unbuffered NON-ECC DDR2-800.8V 128Meg x 64 upgrade for Dell OptiPlex 760 Series (Desktop, Mini Tower and Small Form Factor) system.Though termed a bus, AGP usually supports only a single card at a time ( Legacy bios support issues).IBM's MCA bus, developed for the PS/2 in 1987, was a competitor to ISA, also their design, but fell out of favor due to the ISA's industry-wide acceptance and IBM's licensing of MCA.Installation guides crucial awards.Market Looks to EGA as De Facto Standard, InfoWorld, Aug 19, 1985 Product Comparison: 16-Bit EMS Memory, InfoWorld, Sep 7, 1987 External links edit.Proprietary bus implementations for systems such as the Apple II co-existed with multi-manufacturer standards.The PCI bus was introduced in 1991 as a replacement for ISA.Please refine your selection.
Daughterboards are also sometimes used to expand the basic functionality of an electronic device, such as when a certain model has features added to it and is released as a new or separate model.
