Brand computers are computers with registered trademarks, commonly known as "brand machines", which are produced by microcomputer manufacturers with certain scale and technical strength. The internal structure of brand computers is generally the same as that of ordinary computers. Some world-class brands of computers sometimes use some special structures or special interfaces to achieve better electrical performance and special accessories. Different brands of computers have their own characteristics, maintaining technical support network and paying more attention to after-sales service. We often see in the media that IBM, Hewlett-Packard, Dell and Lenovo all belong to the category of branded computers.
Classification of brand computers
Brand computers can be divided into many grades according to scale, popularity, international and domestic market share and technical support ability.
The products of the first camp are internationally renowned products with strong technical strength. IBM, Hewlett-Packard, Dell, etc., which we are familiar with, all belong to internationally famous brands. Because of the high brand added value, the products of this grade have the highest price under the same configuration, but the stability is extremely high, the configuration is relatively balanced, the hardware quality control is strict, and there will be basically no hardware problems in normal use. There are many computers of this brand, and the appearance has been quite worn out by the unit. Even some things in foreign garbage can still be used normally after being electrified, which is easy to see in the second-hand market. In view of the characteristics of high stability, long mean time between failures and high price, most of these computers are selected by institutions and units, and some of them are selected by individual family users with more budgets.
With strong technical strength, these multinational groups have designed home appliances and computer products for ordinary household users with general computer knowledge. This kind of computer separates the commonly used extended functions through special function keys, which makes the user's operation as simple as possible. At the same time, its appearance gets rid of the traditional computer form and gives people a refreshing feeling with reference to the fashionable design, just like operating an ordinary household appliance.
The second camp produces branded computers for well-known domestic enterprises, which are also very famous in China. With the advantage of localization, after-sales service is also well guaranteed, and some products are also guaranteed nationwide. The computer configuration is close to the needs of domestic users, and the components are universal. Commonly used standard sockets are convenient for users to upgrade with universal accessories in the future. Computer parts are manufactured by designated manufacturers. After many inspections, the finished machine has been tested and baked for a certain period of time before leaving the factory, so that the unpacking qualification rate and renovation rate are controlled at an ideal level. Such products are represented by well-known brands such as Lenovo, Founder and Tsinghua Tongfang. The performance and stability of this grade of computer can basically be comparable to that of foreign brand machines. Some manufacturers have even become international companies, and their products are no different from those of international giants in nature, but the prices are much more favorable.
The brand computers of the third camp are mainly produced by local enterprises with a certain scale and have a certain popularity in specific areas. Products mainly rely on assembly. As a professional unit, the control of computer configuration and hardware quality is more targeted than ordinary users and computer city installers, and it also has certain technical strength and after-sales service ability.
Brand computers in the fourth camp are mostly computers assembled by some small enterprises after applying for brands. Apart from a brand name, they are not much different from compatible machines in essence. Most of these so-called brand computers do not have joint sales outlets, but only rent one or two facades for sale in the computer city, and their after-sales service ability is quite limited. Such computers generally attract customers at low prices, even cheaper than assembling compatible computers. In order to keep profits, users often use their little knowledge of computer hardware configuration and adopt the strategy of high-end CPU with cheap motherboard and low-cost graphics card, which can save money elsewhere. Sometimes it is called "pit configuration" by people in the industry.
The difference between brand computers and compatible computers
It is convenient for users to buy branded computers without considering some hardware configuration details. Some brand-name machines have special customized software, which integrates the common functions of computers and communicates with users through graphical interfaces, making it easy for beginners to get started. Some brands of computers change the commonly used USB interface from the back of the chassis to the front panel of the chassis, which brings great convenience to users who need to use USB interface irregularly (such as users of USB digital cameras). This is more difficult to achieve on compatible computers. Imported brand computers are well wired. When we open the compatible computer chassis and the imported brand computer chassis, we will find that there are great differences inside. I have seen an imported brand computer, and found that its hard disk data cable is porcelain ring to reduce signal distortion, and the length of the whole data cable is just right. This is unimaginable on a compatible computer. At present, most brand computers have their own emergency recovery CD-ROM. Once the computer software system is down, you can recover the computer in a short time (just like you just bought it back). Brands are also intangible assets. Large enterprises pay attention to credibility, and the promised warranty obligations can be fulfilled with good quality and quantity. Many brands also promise door-to-door service. For example, a friend of mine bought an HP brand computer, and the reading ability of the CD-ROM drive decreased, so it needs warranty. Hewlett-Packard's CD-ROM was just out of stock, so it was immediately replaced with a high-speed CD-ROM (no price difference), and promised that if users insisted on using the original low-speed CD-ROM, they could replace it when it was available.
In the eyes of computer enthusiasts, the configuration of high-frequency CPU and mid-range graphics card of brand computers is not as cost-effective as Celeron and high-end graphics cards. In fact, this configuration of brand machines is aimed at the needs of mainstream consumer groups. Computer gamers have very high requirements for game graphics, and most of these users will choose DIY compatible computers. Home users who buy branded computers are often entry-level users with uncertain application scope, but they are generally not professional customers. Using high-speed CPU to process high-end computers will leave a good impression on users, and high-speed processors will also upgrade computer subsystems. For example, the effect of playing ordinary games with mid-range graphics cards and high-speed CPU will not be too bad. When users use office software or other commercial software, high-speed CPU has advantages. For individual users who have special requirements for image processing, brand manufacturers can also provide computers with graphics workstation level.
The biggest advantage of the compatible machine is its low price and flexible configuration. Because compatible machines are mainly parts assembly, there is often no corresponding software cost in China, so the price is much cheaper than that of brand machines of the same grade. The configuration of compatible computers can be described as arbitrary and can be enhanced in some aspects according to personal hobbies. For example, friends who like games choose the best graphics card to make the game effect almost perfect, and friends who like music can choose high-grade sound cards to enjoy more sound effects than ordinary audio. The upgrade space of compatible computers is also relatively large, and multiple interfaces are often reserved on the motherboard, which is convenient for later upgrade and has strong expansibility. The configuration of the whole machine is relatively transparent and the price is flexible. Generally, a set of computers with corresponding levels can be configured, ranging from 4,000 yuan to tens of thousands of yuan. Computer enthusiasts choose accessories to assemble computers according to their own computer knowledge and actual needs, which is called DIY (DIY), which is more suitable for friends who have mastered certain computer hardware collocation skills and market conditions. Although the selected components may all be well-known brands, it is not uncommon to see all kinds of minor faults caused by improper collocation or software problems, which requires consumers to have certain ability to deal with minor problems and not always rely on computer companies. The after-sales service provided by most installers in Computer City is unmatched by brand computers.
Generally speaking, to buy a brand computer is simply to buy a convenient service. If users are not very proficient in computers, or family members are not very familiar with computers, it is better to buy brand-name machines.
What kind of users need to buy brand machines?
Brand computers are obviously not suitable for DIY enthusiasts. As a general household user, there is no special requirement for computers, so it is a good choice to buy branded computers. Brand computers may not be as fast as compatible computers at the same price, but their stability and comprehensive performance are generally better than compatible computers. Frequent crashes or the need to reinstall the system are a headache for even computer experts, not to mention the public users who rarely contact computers. For business users, computers are required to be turned on continuously for a long time, and data is more valuable. It is required to avoid crashes and system crashes as much as possible, so the user brand machine that pays attention to stability is more trustworthy. For users who are not familiar with computers, some brands of computers provide extra shortcut function keys, which are more convenient to use. Therefore, from the perspective of ease of use, brand computers, especially computers with humanized design, are easier to operate, and some computers with beautiful appearance are also easy to integrate with home. Computers need regular maintenance to ensure their stable operation. Computer maintenance can be divided into software maintenance and hardware maintenance. If the user has no maintenance ability, it is best to consider brand computers. Usually their after-sales service is better. Some users need some integrated computers with unique appearance or small size, and only branded computers can do it. For some occasions that require very strict electromagnetic noise or computer equipment that needs to work in a special environment, the performance and technology of brand computers are easier to meet the requirements, and some products with special specifications in brand computers are specially provided for special occasions.
Problems needing attention in purchasing brand machines
When buying a brand computer, you should first decide which brand computer to choose according to your personal budget. If the budget is abundant, and they are naturally positioned as international brands, their quality and operability will never let you down. If users demand cheap and good quality, domestic brand machines (that is, the computers of the second and third camps mentioned above) are also a good choice. Nowadays, many domestic brand machines have diversified shapes and functions, so it is easy for users to choose the computer that suits them. As for the computers in the fourth camp, generally speaking, there is little difference between compatible computers, and sometimes they are not as good as machines assembled on site, so you should be careful when buying such computers. After determining the brand grade, it is necessary to compare the brands of the same grade. Configuration and price, after-sales service and technical support, ease of use and appearance of the computer are all factors to be considered. Finally, after weighing, the brand and model are determined, and the rest is the question of purchase. It is suggested that it is best to buy brand-name machines directly in the specialty store. They have abundant supply, strong technical force and good on-site trial operation. Sometimes you happen to meet a special price and get an extra gift.
Some brands and individual models of computers highlight some functions, such as large-size LCD, which is not necessary for ordinary home users, making the price of computers rise a lot. When purchasing branded computers, especially products with mid-range price, don't excessively pursue some advanced functions or configurations. Brand machines often use the memory capacity of the graphics card to mark the grade of the graphics card configuration, which is unscientific. Users are advised to ask the model and memory capacity of the graphics card chip for comprehensive comparison.
Computers of the same brand are generally graded. Entry-level models are suitable for basic applications and word processing. High-end computers can meet the requirements of most home applications and entertainment. High-end models use the most advanced processors at present, and large-capacity memory is also the basic configuration. They use mid-to high-end graphics cards, and some are equipped with large-size and high-performance LCD monitors, which are generally expensive. For home users, this is the top configuration. Users choose according to their own application needs and budgets.
Brand machines usually provide home computers and commercial computers, as well as high-end graphics workstations and servers according to different purposes. Home computers are mainly enhanced in multimedia and 3D image processing performance. Commercial computers are mainly for office users, with simple configuration and emphasis on the quality and stability of text display. Graphics workstations and servers are generally provided for professional users, and the price is also very high. Different users can choose the corresponding type of computer according to their own needs.
Among many brands of computers in the market, there is a computer called Apple, which is mostly fashionable and beautiful in appearance. This kind of computer does not use the commonly used operating system and application software. Apple computers are superior to ordinary computers in some aspects, but they are not as popular as ordinary computers because of the user groups. Although it has excellent multimedia and 3D graphics processing characteristics, and its appearance is unconventional, from the perspective of universality, users should think carefully before buying.
Users should pay attention to whether to buy imported brand computers. At present, there are many parallel notebook computers, but fortunately there are not many parallel desktop computers. Because international computer manufacturers have factories in China, many foreign computers are made in China. ) Parallel computers usually can't get warranty service and technical support in China unless they are accompanied by a global warranty. Generally speaking, the difference between parallel machines mainly depends on the packaging and the information provided randomly. Parallel computers are usually in English, or the documents are incomplete. In addition to buying from a regular agent, the safest way is to provide the body number of the brand computer to the regional agent of the brand to check whether it is genuine.
Several brands of computers may randomly install non-WINDOWS software to reduce the software cost. Users should try it. If they find that the mainstream operating system is not installed, they should negotiate with the dealer as soon as possible. I believe it is not difficult to install a WINDOWS now.
Pay attention to whether the attached software and accessories are complete when purchasing brand machines for inspection, and check them carefully according to the packing list. General brand machines are pre-installed with operating systems such as WINDOWS XP. Unlike compatible machines, brand machines must be pre-installed with authorized genuine software. In fact, the cost of software has entered the price of the whole machine. Some merchants intercept genuine operating system CDs and authorization certificates and sell them to make money, but users who spend money can't get the CDs. Some computers are bundled with some popular software and free online accounts, which are often intercepted.
For computers used by government departments or confidential departments, especially for bulk purchase, it is best to use domestic well-known brand commercial series computers, so that the quality is guaranteed and it is safer. Because some computers that store confidential data need to install scramblers near the computers, they should buy brand computers with strong shielding performance and small electromagnetic radiation leakage. The extra scramblers have no obvious influence on the operation of the host computer.
Upgrade and Maintenance of Brand Machine
Some brand machines stipulate that users can't open the chassis or replace the internal hardware equipment without permission, otherwise the warranty terms will automatically expire, so be sure to find out whether there are similar terms before opening the chassis during the warranty period. When buying a computer, if you have any questions about the computer configuration, you can directly consult the dealer. If some brand machines are equipped with 256MB of memory, users need 5 12MB of memory, and merchants will generally try their best to solve it for users after proposing it.
The memory upgrade of brand machines, especially imported brand machines, often bothers users. Many memory manufacturers of brand-name machines recommend using products provided by the original factory. Although the quality of these memories is absolutely guaranteed, the high price makes users unwilling. The memory used by many compatible computers in the market is absolutely cheap, but there are many problems when plugged into famous computers, which is very regrettable. In this case, users can go to the local memory chip store and ask if there are any memory chips compatible with their own brand computers for sale. Usually, some compatible brand memory chips can be used with some brands of computers, and the price is much cheaper than the original memory.
Users should carefully read the maintenance terms of brand-name computers. If some brand computers only promise home maintenance of hardware, software problems need to be repaired by users themselves. Some computers come with emergency recovery discs. When the system can't work normally due to software failure, you can use the emergency recovery CD to quickly reinstall the system. However, users should think carefully before using the CD. Although some emergency recovery discs can restore the computer software to the factory state, the software and stored data installed by users in the early stage will be overwritten and completely lost, so backup work must be done before this.
Generally speaking, branded computers are suitable for "using" the home, but not for "playing" the home. There are also some skills and precautions for purchasing brand computers, which are also helpful to compare with professionals.
