What are the types of motherboard slots?

The motherboard slot types are: 1. ISA, which is an expansion slot based on the ISA bus; 2. PCI, which is an expansion slot based on the PCI local bus; 3. AGP slot; 4. AMR slot ; 5. CNR slot; 6. ACR slot; 7. Special-PCI slot.

The operating environment of this tutorial: Windows 10 system, Dell G3 computer.

The expansion slots on the motherboard mainly include the following types:

1. ISA

The ISA slot is an expansion slot based on the ISA bus. , its color is generally black, longer than the PCI interface slot, located at the bottom of the motherboard, and can be plugged into expansion cards such as graphics cards, sound cards, network cards, and so-called multi-function interface cards.

2. PCI

is an expansion slot based on the PCI local bus. Its color is generally milky white. It is located below the AGP slot on the motherboard and above the ISA slot. It can plug in a graphics card. , sound cards, network cards, video capture cards and a wide variety of other expansion cards. The PCI slot is the main expansion slot of 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. The AGP slot is usually brown. It is not at the same level as the PCI and ISA slots, but is further inward.

4. AMR slot

AMR (Audio Modem Riser, sound and modem card) specifications, its location is generally near the PCI slot (white), relatively short (about only 5 cm), with a brown appearance. Can plug in AMR sound card or AMR Modem card.

5, CNR

CNR (CommunicATIon Network Riser, communication network card) slot color is brown, supported card types are Audio CNR, Modem CNR, USB Hub CNR, Home PNA CNR, LAN CNR, etc.

6, ACR

The ACR plug-in 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 ACR slots are designed to be placed where the original ISA slot was. They adopt a 120-pin design and are compatible with ordinary PCI slots.

7. Special-PCI

PCI-Express is the latest bus and interface standard. Its main advantage is its high data transfer rate, currently up to 10GB/s and more. Considerable development potential. PCI Express also has a variety of specifications, from PCI Express 1X to PCI Express 16X, which can meet the needs of low-speed devices and high-speed devices that appear within a certain period of time.
