0 Basic Learning Computer hardware knowledge

The motherboard is a platform, the CPU, memory, graphics, hard disk, optical drive through the data cable or directly installed to form a working whole. CPU equivalent to the human brain, issued a variety of instructions to coordinate the work of various parts, memory is a transit warehouse, the transfer of various instructions, data and so on. After shutdown data is not retained, the hard drive is the final carrier, all data, programs, songs, movies and so on are saved in the hard drive The data on the hard disk is left behind when the computer is shut down. The chassis is the whole fixed in a fixed environment, through the power supply to each part of the power supply, through the graphics card to output display signal, The final display is displayed on the monitor. The keyboard and mouse are used to perform various operations on the computer. The sound box outputs a variety of sounds through an integrated sound card on the motherboard. The network card is to send and receive data when building a local area network or surfing the Internet. The hardware of the computer is all hardware, What you can't touch is software. Computer hardware Under normal circumstances is not easy to damage, only the software aspects of the problem is more, only the software to eliminate all the trouble after the final consideration of hardware problems.

　　Cpu:

The current common CPU is mainly produced by 2 manufacturers, one is AMD, high-end products are Speed Dragon series, the low-end is the Flash Dragon series, the other is inter company, high-end products are Ben 4 series, the low-end is the Celeron series. Two-year-old dual-core CPUs have a corresponding model in the high-end products of 2 companies. The knowledge of the CPU is more, the concrete can inquire on the net again, here is not more to say. Reminder, the CPU is not made false, only outside the box, fans and other accessories exist fakes.

　　Motherboard:

The current motherboard main chip are foreign-made, chip manufacturers are mainly nvidia,ati,inter,amd,via,sis, and so on, major motherboard manufacturers to develop their own PCB board design, respectively to meet the CPU needs of 2 CPU manufacturers.

　　Graphics:

The current graphics card is divided into independent and integrated graphics, the production of independent graphics chips are mainly 2 manufacturers monopoly, NVIDIA and ATI, production integrated graphics chip has inter,nvidia,ati,sis and so on. Major graphics card manufacturers to use the graphics card chip provided by the GPU graphics card design and assembly .

　　Memory:

At present all the memory of the particles are made abroad, mainly made in Korea. Domestic production is only PCB board and encapsulation process. There are mainly 3 kinds of memory, one is SD memory (OBSOLETE), one is DDR memory, the other is DDR II memory. There will be DDR III memory in the future.

　　Hard disk:

Common hard drives are Samsung, West and Seagate, is basically Seagate a solo show, the capacity of more than 20GB is basically 7400 rpm, below 20GB is generally 5400 rpm, the higher the speed, the faster the hard disk read some data. Note: Hard disk production environment requirements are relatively high, All the hard drives are produced abroad.

　　Chassis + power supply:

These two things have no technical content, are domestic manufacturing.

　　Drive:

Common have CD-ROM (similar to VCD machine), CD burner (compatible with VCD, you can burn VCD), DVD optical drive (similar to DVD player, compatible VCD), combo (the equivalent of DVD optical drive more than a VCD CD-ROM function), DVD burner (Vcd,dvd play and VCD, DVD burning feature)

　　Display:

There are two common types, CRT and LCD, one is a general display, one is a liquid crystal display, the common development process of ordinary display and TV similar, size from 14 15 17 19 21, screen from the spherical Jia Chunping physical flat. LCD display size from 14 15 17 19 inch, The current popular widescreen has 17 19 20 21 inches and so on. LCD monitors are made of liquid crystal panels from abroad.

　　Sound:

Common with integrated sound card and independent sound card, the vast majority of motherboards are integrated with integrated sound card, can meet the average consumer is the use. Independent sound cards are generally used in high-end, here is not much to say.

　　Card:

Common have independent and integrated network card, the majority of motherboards are integrated with integrated network card, can meet the use of ordinary consumers, independent network card mainly applied to special requirements of the user. There's not much to say here.

　　Keyboard + Mouse:

Relatively no technical content, belongs to the loss of goods. It's about personal preference.

　　Speaker + Headset:

Relatively no technical content, belongs to the loss of goods. It's related to personal preference.

　　Floppy drive:

Basically eliminated, here is not discussed.
