- PCI Slots
- Expansion slots based on PCI local bus
- Color is generally milky white
- Located below the motherboard AGP slot, above the ISA slot
- Bit width 32bit or 64bit, operating frequency is more than 33MHz
- Pluggable graphics card, sound card, network card, internal modem,usb2.0 card
- is the main expansion slot of the motherboard, through the docking of different expansion cards can be achieved by the computer to achieve almost all functions, is a universal expansion slot
- Development process
- The basic 33MHz is 133mb/s bandwidth, more than enough for sound cards, network cards, but not for the graphics card to meet their needs
- Even the upgraded 66MHz will not meet the graphics card requirements
- Intel announced the third-generation I/O technology that replaced the PCI bus in 2001, 2002 finalized and finally officially named PCI Express
- 2002 introduced the pci-e1.0 specification, 2007 introduced 2.0 specifications, mainstream graphics are supported pci-e2.0
- AGP Slots
- Accelerated Graphics Port
- Developed on the basis of PCI bus, in order to alleviate the video bandwidth tension and establish, mainly for the graphic display aspects of optimization, specifically for graphic display card
- The AGP slots are usually brown, and the PCI, ISA slots are not on the same horizontal line, and some are built into
- With the increased speed of the graphics card, the AGP slot has not been able to meet the speed of data transmission, the AGP graphics card has been gradually eliminated, replacing it is the PCI-E slot
- Version
- AGP 1.0 (agp1x agp2x) 1996
- AGP 2.0 (AGP4X) 1998
- AGP3.0 (agp8x) 2000
- ISA slots
- Based on the ISA bus, Industrial standard Architecture industrial standards Architecture Bus
- The color is generally black, longer than the PCI interface, at the bottom of the host
- Plug-in card, sound card, network card and so-called multi-function interface card and other expansion card
- Cons: CPU resource consumption is too high, data transmission bandwidth is too small, is already eliminated slot interface
