PCI (Peripheral Component Interconnect)
As Abbreviation for Peripheral Component Interconnect PCI is a bus standard that can be used in a variety of ways to use peripheral devices to the computer. The first version was introduced by Intel in 1991 as a successor to the ISA standards and since about 1994 has virtually any PC via one or more PCI slots on the motherboard. Also, there are matched variants, such as PCI Extended (PCI-X) for servers and PCI Express (PCI-E or PCIe), the latter especially in the area of ??graphics cards is used. In addition to our used computers with a PCI slot, we offer a wide variety of cars with PCI expansion cards, so you can customize your system according to your wishes.
What are the differences between the various PCI cards are there?
First, a distinction is made between two different signal voltages. PCI cards with a notch on the left (in the direction bracket) are compatible with 3.3 V, corresponding to a notch is right for compatibility with a 5 V signal voltage. Likewise, the slots are coded on the motherboard. Universal cards have both notches and can be operated in both slots. If a card is not compatible, it can not be installed, so should be taken with a high pressure here never to avoid damage. PCI 3.0 is the latest version and has a land left in the slot, so here are exclusively supported 3.3 V and universal cards. Previously on PCI 2.x was the bridge on the right side, support for 5V cards, however, was abolished as PCI 2.3. However, the cards fit physically in the 2.3 slot and some motherboards come so readily apparent. If there is any doubt here that the manual and the manufacturer's documentation should be consulted. In addition, distinction is made between the profiles designs standard and low, which refer to the card length and height. In general it can indeed say that the designs are incompatible with each other, under certain circumstances, however, a low profile PCIKarte be used in the standard slot. Does the size of the card to this, the bracket can be replaced on the card and the insertion succeeds then. The low profile design is particularly useful for small form factor computers are used.
What is needed PCI-Extended
In contrast to herkö , mmlichen PCI is the bus-width PCI-X 64 bit instead of the previous 32 bits. Therefore, this variant is especially useful for servers that are frequent and there is eg used for Gigabit network cards or RAID controller. Recognize it can be to much longer slots and contact strips on the cards. The available signal voltages are, however, similar to the normal PCI. Caution shall be exercised, however, when 32-bit card in a 64 bit slot will operate, as this slows down the entire bus and other cards, such as RAID controllers are limited in throughput. The coexistence of 32 and 64 bit slots on a motherboard, however, is not a problem and is more common. Here you can find also used motherboards with these properties.
Which functions can be provided by PCI cards?
With PCI you have High expandability. Most often, you will be used to retrofit certain interfaces, such as LAN, WLAN, COM, LPT, or USB. In the field of telecommunications, ie for modems and ISDN adapters, PCI is often used. In the area of ??graphics cards and RAID controllers while there are also several PCI models, but preferably the PCI Express standard is here, because of the speed used today.
