Today's content is calculated, from the basic knowledge of computer assembly, to the main board identification and purchase, CPU identification and purchase, memory identification and purchase, hard drive identification and purchase, optical drive identification and purchase, The identification of graphics cards and displays is to purchase this seven major components that make up today's review content. Because tomorrow is going to start the exam, although it is not very good, learn to have some gaps with them, but how much is your own summary.
The computer consists of two parts of the hardware system and software system. The role of the hardware part or is functional, what should I explain? Computer hardware is a physical device that must exist in a computer. The operation of any software has a hardware system. Software is to run, manage, and maintain computer systems, and give full play to the sum of various procedures prepared by computer performance, generally divided into system software, programming language and application software.
Computer hardware mainly refers to computer physical devices, hardware systems are divided into hosts and peripherals, including: motherboard, CPU, memory, hard drive, floppy drive, optical drive, graphics card, sound card, chassis, power supply, etc., computer peripherals Includes: Display, Keyboard, Mouse, Speaker, Printer, Scanner, Fax, Game Handle, etc. Popular point, that is, all parts of the host belong to the host, and who is outside the external peripherals.
The main board manufacturing technology has the following aspects:
Manufacturing standard standard technology, which mainly includes two comparison of NSTL Y2K test certifications and PC technical specifications.
Convenient technology: free jumper technology, BIOS upgrade technology, motherboard energy, overclocking technology.
Security technology
Telling so much about the main board, how can I choose a computer motherboard with a cost-effective price?
The motherboard is an integrated product that integrates high-tech and high processes. Therefore, we first consider the "brand" of the motherboard, and the popular motherboard brand has ASUS, MICO-STAR, Gigabyte (Giga) -Byte, Soltek, Intel, 英 (EPOX), Lenovo (QDI), Diamond (DFI), Elite (ECS), Mercedes-Benz (PARADISE) and other brands.
In addition to purchasing the brand of the computer's motherboard, it should also be started from the various manufacturing techniques of the motherboard. The first is the manufacturing process, and the method of manufacturing process: Whether the main board works fine, the welding joints and the peak solder joints are simple, whether it is simple and clear; the other is to look at the main board components; three design structures are compliant In the future, upgrade installation is required, whether the structure layout is reasonable, is conducive to the installation of other parts and heat dissipation devices; four ways to watch the safety standards by the corresponding safety standards; finally look at the various cables, driving disks, and warranty of the main board, drive Whether the card is complete.
PCB board, ie printed circuit board, now most of the PCBs are designed with a 4-layer board, and there is a better performance of excellent motherboard PCB boards.
Upgrade and expand, the ability to extend memory modules and increase expansion cards, upgrade CPUs, etc., the better the expansion, but the price is more expensive.
Then, the main board is integrated, the integrated motherboard uses a highly integrated chipset, and integrated sound card, graphics card, and modem chip, such a motherboard has the advantages of simple layout, low cost, high integration, and high cost performance.
Finally, how to detect the quality of the motherboard. There are several methods: the main board battery, observe whether the battery rusts and leaks; the production date of the chip, the speed of the motherboard is not only on the speed of the CPU, but also depends on the performance of the motherboard chipset, the closer the production date of the chip. In the purchase date, the performance is relatively better in the same brand; the expansion slot card, the method is to carefully observe the position of the slotted spring sheet, shape, and then pull out the expansion card into the groove, observe within the groove The position of the spring is the same, the shape is the same; the software speed is used to understand the performance of the motherboard, preferably the SPEED series and the SST series of speed measurement software. Ok, write here first. Let's take a break.
