DIY installation instructions Xiaobai must see computer hardware knowledge
Many friends who use computers, do not learn computer hardware knowledge, many common sense students can not solve the problem, often feel the need for computer knowledge popularization, there are many basic knowledge can help to better learn computer applications. Here is a brief introduction to the composition of computer hardware. Let the friends who want to learn computer hardware and are unfamiliar with the hardware understand, starting from the simple, starting from the basics.
Put the CPU, the motherboard is a platform, the memory, graphics card, hard disk, optical drive through the data line or direct device to form a whole work.
The CPU is equivalent to the human brain, and issues various instructions to coordinate the work of various parts. The memory is a transit warehouse, which transfers various command data and so on. After the shutdown, the data is not retained, the hard disk is the final carrier, all data, order, songs, movies, etc. are kept in the hard disk, and the data in the hard disk is retained after being turned off. The chassis is to fix the whole in a fixed environment, power is supplied to each part through the power supply, the display signal is output through the graphics card, and finally displayed on the display. Keyboard and mouse to carry out various operations of the computer. The speakers output a variety of sounds through the integrated sound card on the motherboard. The NIC sends and receives data when the LAN is set up or when it is connected to the Internet. The hardware of the computer is said to be the hardware that can be touched. If it is not touched, it belongs to the software. Computer hardware is generally not easy to damage, only software problems are more, only the software side of the fault is completely ruled out and finally consider the hardware.
First, the motherboard
The main chips of the current motherboards are all made in foreign countries. The chip manufacturers mainly have NVIDIA, ATI, INTER, AMD, VIA, SIS, etc. The major motherboard manufacturers develop their own PCB boards to design the motherboards to meet 2 CPUs. The manufacturer's CPU needs.
CPU:
At present, the common desktop CPU is mainly produced by two manufacturers, one is AMD, the middle and high-end products are Athlon series, the low end is Sempron series, the other is Intel company, the high-end product is Core series, the low-end is Pentium The series, the low end is the Celeron series. As a reminder, the CPU can't make a fake, only the outer box, the fan and other accessories have fakes.
Graphics card:
The production of independent graphics chips is mainly monopolized by two manufacturers. The current graphics cards are divided into independent and integrated graphics cards. NVIDIA and ATI, the integrated graphics chip has INTER, NVIDIA, ATI, SIS and so on. The major graphics card manufacturers use the graphics card GPU provided by the graphics chip to design and assemble the graphics card.

a('show4');RAM:
Mainly made in Korea. Domestic is just the process of producing PCB boards and packages. There are three main types of memory, and all the memory particles are currently made in foreign countries. One is SD memory (deprecated), one is DDR memory, one is DDR 2 generation memory and the current mainstream DDR 3 generation memory, DDR4 memory will also become popular in the future.
"Lithium battery" refers to a battery made of lithium metal or lithium alloy as a negative electrode material, using a non-aqueous electrolyte solution.It has a high energy density.Compared with high-capacity nickel-cadmium batteries, the energy density is twice as high.High voltage. The average service voltage is 3.6v, which is three times higher than nickel-cadmium and nickel-hydride batteries.The use voltage is even and the high capacity, the widespread use temperature -20 degrees -60 degrees, the charge and discharge life is long, after 500 discharges its capacity at least has more than 70%.Due to the characteristics of high energy density, high voltage and stable operation, lithium battery is widely used.
