What are the slot types of the computer motherboard?
This article introduces what are the slot types of the computer motherboard, the content is very detailed, interested friends can refer to, I hope it can be helpful to you.
There are mainly the following types of expansion slots on the motherboard:
1 、 ISA
ISA slot is based on ISA bus expansion slot, its color is generally black, longer than the PCI interface slot, located at the bottom of the motherboard, pluggable video card, sound card, network card, and so-called multi-function interface card and other expansion cards.
2 、 PCI
Is based on the PCI local bus expansion slot, its color is generally milky white, located on the motherboard below the AGP slot, above the ISA slot, can plug in video card, sound card, network card, video capture card and other kinds of expansion cards. The PCI slot is the main expansion slot for the motherboard.
3 、 AGP
AGP (Accelerated Graphics Port) is developed on the basis of PCI bus. It is mainly optimized for graphics display and is specially used for graphics display cards. AGP slots are usually brown, and they are not in the same horizontal position as PCI and ISA slots, but are inward.
4. AMR slot
AMR (Audio Modem Riser, Voice and Modem plug-in Card) specification, which is usually located near the PCI slot (white), is relatively short (about 5 cm) and has a brown appearance. AMR sound card or AMR Modem card can be plugged in.
5 、 CNR
The CNR (CommunicATIon Network Riser) slot is brown, and the supported card types are Audio CNR, Modem CNR, USB Hub CNR, Home PNA CNR, LAN CNR and so on.
6 、 ACR
The ACR card can provide functions such as Modem, LAN (local area network), Home PNA, broadband network (ADSL, Cable Modem), wireless network and multi-channel sound processing. Most of the ACR slots are designed to be placed in the original ISA slot, with a 120-pin design, compatible with ordinary PCI slots.
7. Special-PCI
PCI-Express is the latest bus and interface standard, and its main advantage is its high data transmission rate, which can reach more than 10GB/s at present, and has considerable potential for development. PCI Express also has a variety of specifications, from PCI Express 1x to PCI Express 16X, which can meet the needs of low-speed and high-speed devices that appear in a certain period of time.
About the computer motherboard slot type which shares here, hoped that the above content can have the certain help to everybody, can learn more knowledge. If you think the article is good, you can share it for more people to see.
