Motherboard is also called motherboard, motherboard, system board, etc.
In a microcomputer, the main circuit system of the computer is installed on the motherboard, with expansion slots and various plug-ins inserted. The quality of the computer has a great relationship with the design and technology of the motherboard. Therefore, since the birth of computers, manufacturers and users have attached great importance to the architecture and processing level of motherboards. Knowing the characteristics and usage of the motherboard is very valuable for choosing, installing and using the machine. Next, introduce the main technical characteristics and related problems of Pentium-class motherboard and Pentium-class motherboard, which are popular at present.
New technology on the motherboard
The technical update of the computer industry is undoubtedly the most frequent and rapid. Generally, it only takes 1 ~ 2 years for a motherboard to be put into market for elimination. At present, the motherboards sold in the market generally adopt some common new technologies, and there are some similarities. Mainly: using Flash BIOS, users only need to upgrade their software; Using synchronous burst (PB Cache) two-level cache can improve the speed and efficiency compared with the previous asynchronous cache. The motherboard integrates two serial ports, a parallel port and a floppy drive interface; The motherboard integrates two enhanced (EIDE) hard disk interfaces for connecting hard disks, IDE optical drives, tape drives and other devices. Some motherboards also have PS/2 mouse port, universal serial bus (USB), DMI resource management, etc.

Supported memory types refer to specific memory types supported by the motherboard. Different motherboards support different types of memory. Memory types mainly include FPM, EDO, SDRAM, RDRAM and DDR DRAM.
ECC is not a memory type. ECC (Error Correction Coding or Error Detection and Correction) is a kind of memory with automatic error correction function. Intel's 82430HX chipset began to support. Motherboards using this chipset can install and use ECC memory. However, due to the high memory cost of ECC, it is mainly used in commercial computers with high requirements for system reliability, such as servers/workstations. In fact, memory errors do not occur frequently, and ordinary motherboards do not support ECC memory, so ordinary home and office computers do not need to use ECC memory.
Generally speaking, the motherboard only supports one memory type, but there are exceptions. Some motherboards have two kinds of memory slots, and you can use both kinds of memory. For example, some motherboards used to use EDO and SDRAM, but now some motherboards can use SDRAM and DDR SDRAM.
IBM scientists develop new memory chips
In order to make smaller electronic devices, manufacturers of consumer electronic products constantly increase the capacity of memory chips or hard disks to accommodate data storage.
This trend makes mainframes shrink to desktops, then to laptops, so that they become devices in our clothes pockets.
Now, if the idea of Stuart S. P. Parkin, an IBM laboratory scientist, is funded, the data of 10 to 100 times can be stored in the existing electronic equipment with the same area. This means that an iPod player that can store up to 200 hours of video programs at present can store 120 TV channels for one week.
Video card is an essential equipment of the system, which is responsible for processing the image data sent by CPU into a format that the display can understand, and then sending it to the screen to form an image. It is the most important channel for us to get information from the computer. So the graphics card and monitor are one of the most important parts of the computer.
Display plays a very important role in stability, brightness, stability and maximum resolution. If you want to have high-quality images, you need a high-quality large-screen display, at least 17 inch, and your graphics card should be the best. If the monitor is broken, it will look uncomfortable.
Screen resolution and color resolution are related to the size of video RAM.
The performance of the graphics card is related to the type of chip. But don't forget, it is also related to the bus (PCI/ISA/EISA), so the motherboard and its chipset are related to the speed at which data reaches the graphics card. Finally, the MMX instruction set added by Pentium (P55C)/ Pentium Pro (Klamath)/6x86 (M2) CPU can improve the performance of graphics cards, which may be more helpful than any current graphics card technology.
The emergence of new specifications such as DX 10, DDR4 memory and 80nm technology is definitely a new hot spot in the development of graphics card technology. NVIDIA released —G80, the world's first graphics core supporting DX 10, and ATI launched —x 1950 txt, the first DDR4 memory graphics card in DIY market. The core technology of many mainstream graphics cards has turned to 80nm, which has had a great impact on the graphics card market. Now I also expect the graphics card technology and hardware specifications in the next few years.
Up to now, the concept of display has not been unified, but the understanding of it is mostly the same. As the name implies, it should be a display tool that displays some electronic files on the screen through a specific transmission device and then reflects them to the human eye. Broadly speaking, the large screens that can be seen everywhere on the street, such as TV, mobile phone, fast translation and other display screens, all belong to the category of monitors, but at present they generally refer to display devices connected to computer hosts. It is widely used, from satellite monitoring to watching VCD. It can be said that it is everywhere in modern society.

LG。 Philips has been trying hard to find ways to make displays that are beneficial to users' eyes, which is one of the important factors for it to maintain its advantage in the global display market.
This time, it will launch an antifouling LCD. It has developed a liquid crystal panel made of a new technology similar to a pen-free oil-based pen, which will not be stained with oil, dust or even fingerprints and permanent ink. It sounds really amazing, and I believe it can also solve the long-term trouble of LCD users, because once it is stained with the above stains, it will be super troublesome. However, it is said that this panel will not be mass-produced until the first half of 2008, but it will certainly be welcomed by many friends.

Hard disk is an important part of computer, and it has become the most important member of computer external memory because of its large capacity, fast storage speed, stability and safety. Computer operating system, application software and computer games can only be used when they are installed on the hard disk, and data such as files and pictures created by users can only be stored on the hard disk. When a computer performs an operation, the hard disk plays the role of transferring data to memory for CPU to perform the operation, and then storing the operation result. In short, the hard disk is the task.
The glass substrate of computer hard disk drive is a disk used to store media information. Most of the materials used now are aluminum alloy substrates. With the rapid development of computer, when the speed of hard disk reaches 10000rpm, aluminum alloy can no longer meet the requirements of temperature deformation resistance. Glass-ceramic substrate has the characteristics of high heat resistance, high mechanical strength, low expansion and ultra-smooth surface, and can replace aluminum alloy substrate. Its annual output is about 40 million pieces, accounting for about 10% of the whole substrate market. Replacing aluminum substrate with glass substrate is an inevitable trend of computer development, and its market prospect at home and abroad will be very broad.
Optical drive is a common accessory in desktop. With the more and more extensive application of multimedia, CD-ROM has become the standard configuration of many desktop accessories. At present, optical drives can be divided into CD-ROM drives, DVD-ROM drives, COMBO drives and burners.
Nbsp; CD-ROM: Also known as CD-ROM, it is a read-only optical storage medium. It was developed by using the CD-DA (Digital Audio) format originally used for audio CDs.
NbspDVD drive: It is a drive that can read DVD discs. Besides the common formats such as DVD-ROM, DVD-VIDEO, DVD-R and CD-ROM, it should also support CD-R/RW, CD-I, VIDEO-CD, CD-G and so on.
NbspCOMBO optical drive: "Kangbao" optical drive is the common name of COMBO optical drive. COMBO optical drive is a multifunctional optical storage product which integrates CD burning, CD-ROM and DVD-ROM.
Nbsp; CD-ROM drive: including CD-R, CD-RW and DVD burner, among which DVD burner is divided into DVD+R, DVD+RW, DVD-RW(W stands for erasable) and DVD-RAM. The appearance of a burner is similar to that of an ordinary CD-ROM drive, except that three speeds of writing, copying and reading are usually clearly marked on the front panel.

At present, the global optical drive market is huge, but the optical drive technology has been controlled by a few developed countries. Recently, Shenzhen Jinfenglong Digital Technology Co., Ltd. has developed the OVK precision magnetic core with independent intellectual property rights, and applied it to computer optical drives, obtaining dozens of China patents, breaking the monopoly of foreign optical drive development. In the international market, computer CD-ROMs have always used in-and-out movement. The biggest advantages of the suction computer optical drive technology developed by the company are low noise performance, compatibility of large and small disks, and good quality of reading and writing disks. But the price is almost the same as that of the ordinary CD-ROM drive. This superior cost performance will have an impact on the market, and will greatly accelerate the technological upgrading of the optical drive industry. In addition, this technology can also be widely used in high-definition multimedia industry, including red and blue light technology, as well as various optical storage applications in automotive electronics industry. Computer CD products with this new technology have been put on the market.
ü sound card
Sound card is the most basic part of multimedia technology, and it is a kind of hardware to realize the conversion between sound wave and digital signal. The basic function of sound card is to convert the original sound signals of microphone, magnetic tape and CD-ROM drive, and output them to headphones, speakers, power amplifiers, tape recorders and other audio devices, or make musical instruments make beautiful sounds through MIDI.
Not long ago, HardOCP revealed the latest plan of the innovative company in the sound card market. The most attractive part of this plan is the release of a new sound processing chip in the middle of this summer.
The new sound card will be based on EMU 10K2 sound processing chip. The innovation of this new sound processing chip lies not only in enhanced performance, but also in supporting more functions:
