Business office computer
Business office computers are generally used to process documents, send and receive mail, make forms, and so on. The requirements of the computer require the computer host to run stably for a long time, and the configuration requirements for the computer are not high, and the low-end computer configuration can be used.
2. Family computer
The configuration of the home computer does not need to be too high, it only needs to be used daily, and the computer with medium and low configuration is fully competent. The main purpose in the general family is to browse the web, handle simple documents, watch audio and video, or play a small game, low-end computer configuration.
3. Design drawing computer
If you need to process a large number of picture graphics during the use of the computer, the workload is enormous. The requirements of the graphics card are very high.

4. Game entertainment computer
If you want to buy a computer for large games, the overall demand for the computer is very high. Currently, most of the games on the market are 3D games. Such games have higher memory capacity, especially graphics cards and CPU requirements. The configuration of the best game that you usually play requires to match.
Second, make it clear whether you are buying a desktop computer or a notebook
The rapid development of the notebook makes it cheaper, and it has become the target of people's choice. According to different needs, the choices are different. For those who are hesitant to choose a computer or a notebook, you can refer to the following points:
1. Application environment
The advantage of the desktop is that it has high performance and the disadvantage is that it occupies a large area, so it is more suitable for fixed use at home or office. In addition, the desktop is more cost-effective and has a price advantage. The advantage of the notebook is that it is small in size and portability. The disadvantage is that the performance is not as high as that of the desktop, but the portability is excellent.
2. Performance requirements
In desktop computers and notebooks of the same price, desktop computers are higher than notebooks. And desktop computers are also more scalable, so for high-demand friends choose a desktop computer. Of course, some high-profile notebooks, performance has reached a very good level, but the price will be more expensive.
3. Price demand
The price/performance advantage of a laptop is not as good as that of a desktop computer. If you consider the price, you should give priority to desktop computers.
3. Determine whether to buy a brand machine or an assembly machine
There are two types of desktop computers: one is a brand machine and the other is a brand assembly machine.
Brand machines refer to independent brands of computers, such as Lenovo, Hewlett-Packard, Dell, Apple, etc. These are sold by professional computer manufacturers of certain scale and advanced technology, with registered trademarks, and perfect after-sales system. High, quality assurance, try to choose this type of brand machine, but now young people do not buy brand machines, because the configuration is low, can not play large games.
The assembly machine means that the user can freely match the accessories, and can be configured according to their own needs. For example, if you play a large game, then I can buy the CPU and the graphics card a little better. If you don't play the game, then I can not match the discrete graphics card, the integrated graphics card. can. The assembly machine is flexible and cost-effective, and can be upgraded at any time according to its own needs after purchase.
Know the computer performance indicators before buying a computer:
Performance is a measure of the quality of a computer, but it does not refer to the quality of a component, mainly refers to the overall performance, judged by the indicators of the following major components.
1. CPU: The most common CPU on the market is the two brands of intel and AMD. Among them, Intel occupies more than half of the desktop PC market. The computing speed of the CPU is an important indicator to measure the performance of the computer. It is usually described by the frequency of the main frequency. Nowadays, the dual-core CPU popular in the market adopts multi-core technology while the main frequency speed is increased. The higher the overall frequency, the faster the computing speed.
2. Graphics card: The most common graphics card on the market is ATI, NVIDA brand. The graphics card is divided into discrete graphics card and integrated graphics card. The role of the graphics card: the graphics card is to process the image data sent by the CPU into a format that the display can receive, and then send it to the display. Form a picture on it.
a('show4');3. Memory: It is the memory directly accessed by the CPU. All the programs that need to be executed and the data to be processed in the computer must be read into the memory first. The memory size reflects the ability of the computer to store information in real time. With the upgrade of the operating system and the increasing functions of the application software, the demand for memory is increasing.
The above small series of some suggestions for computer purchase, I hope to help everyone.
The Paper Holder includes a rack body and a rack shaft. The rack body includes a left baffle, a right baffle and a wall plate. At the rear end of the chute, the two ends of the frame shaft are respectively connected by sliding or rolling with the chute on both sides of the frame body, and the wall plate has a boss parallel to the frame shaft, which overcomes the shortcomings of the prior art and provides a method that only uses one The paper roll holder that can tear the paper by hand. The described technical solution adopts the paper jam structure in which the movable frame shaft structure of the slideway and the frame shaft is combined with the boss on the frame body, so as to realize the use of one hand The process of pulling and breaking the paper can be completed, which is very convenient to use.
