1. English abbreviation for motherboard
Motherboard, also known as motherboard, system board, and motherboard; It is installed inside the computer case and is one of the most basic and important components of a microcomputer. The motherboard is generally a rectangular circuit board, on which the main circuit systems that make up the computer are installed, including BIOS chips, I/O control chips, keyboard and panel control switch interfaces, indicator light connectors, expansion slots, DC power supply connectors for the motherboard and card insertion, and other components. Another characteristic of the motherboard is the adoption of an open structure. Most motherboards have 6-8 expansion slots for PC peripheral device control cards (adapters) to be plugged in. By replacing these cards, local upgrades can be made to the corresponding subsystems of the microcomputer, giving manufacturers and users greater flexibility in configuring the model. In short, the motherboard plays a crucial role in the entire microcomputer system. It can be said that the type and grade of the motherboard determine the type and grade of the entire microcomputer system, and the performance of the motherboard affects the performance of the entire microcomputer system. There are several common ways to classify PC motherboards: ★ Motherboard classification:
1. According to the CPU used on the motherboard, there are 386 motherboard, 486 motherboard, Pentium (586) motherboard, and Pentium Pro (686) motherboard. CPUs of the same level often have further divisions, such as whether they support multi energy Pentium (P55C, MMX requires dual voltage built-in on the motherboard), whether they support Cyrix 6x8
6, AMD 5k86 (both are Pent
Secondly, according to the type of I/O bus on the motherboard, ISA (Industry Standard Architecture) industrial standard architecture bus is used.
·EISA (Extension Industry Standard Architecture) extends the standard architecture bus ·MCA (Micro Channel) microchannel bus In addition, in order to solve the bottleneck problem of slow transmission speed between CPU and high-speed peripherals, two types of local buses have emerged, which are: VESA (Video Electronic Standards Association) local bus, abbreviated as VL bus ·PCI (Peripheral Component Interconnect) is a local bus that interconnects peripheral components 486 level motherboards mostly use VL bus, while Pentium motherboards mostly use PCI bus. At present, after PCI, more peripheral interface buses have been developed, which are USB (Universal Serial Bus). IEEE1394 (Institute of Electrical and Electronics Engineers 1394 standard) is commonly known as "Fire Ware".Thirdly, logically control the chipset. These chipsets integrate control over CPU, CACHE, I/O, and bus, and motherboards above 586 attach great importance to the role of the chipset.
. The chipset produced by Intel for the 586 motherboard includes the LX early chipset for Pentium 60 and 66MHz CPUs, NX Neptune, which supports CPUs above Pentium 75 MHz. It was popular before the release of the Intel 430 FX chipset and is now rare. ·FX has this chipset in both the 430 and 440 series, with the former used for Pentium and the latter for Pentium Pro. HX Intel 430 series, used for commercial microcomputers with high reliability requirements. The VX Intel 430 series has been optimized and streamlined for ordinary mu
