The memory type of a video card is the type of RAM that is used on the video card. Most modern cards use GDDR5 which is essentially DDR3 RAM that has been optimized for graphical operations. Some basic video cards simply use DDR3 RAM, but sacrifice a decent amount of memory performance by doing so. Until a new version of video RAM is released, GDDR5 and DDR3 are the only two versions that.
An expansion slot of a computer motherboard is used to accept the expansion card or expansion board, adapter card or accessory card to add additional functionality to a computer system. There are many types of expansion slots used in today's computers. They are ISA, PCI, AGP, PCIe, AMR, and CNR expansion slot. Each type differs in appearance and function.
Figure 10-2 shows a standard brown AGP 3.0 video expansion slot, located between the white PCI slot and the chipset heatsink at the top of the image. Note the keying tab in the body of the slot, located to the right of center, toward the front of the system. AGP RETENTION MECHANISMS. Note the retention mechanism on the right end of the slot, which is similar to the PCIe retention mechanism.
In computing, an expansion card, expansion board, adapter card or accessory card is a printed circuit board that can be inserted into an electrical connector, or expansion slot, on a computer motherboard, backplane or riser card to add functionality to a computer system via the expansion bus. An expansion bus is a computer bus which moves information between the internal hardware of a computer.
Expansion Card Tip: Any expansion card needs to fit into a compatible slot on your motherboard, such as a PCI or PCI-Express slot. If your current system doesn’t support the type of expansion card you want, you may be able to upgrade to a new motherboard with the proper interface slots.
A slot card is a modular expansion card, which can be inserted into a free expansion slot in a PC computer. Most popular types of slot cards are graphic cards, sound cards, TV tuner cards and.
