These belong to the maintenance industry, and ordinary colleges and universities have nothing to learn. Only those training technical schools need to learn, or go to the store to find a special maintenance master to learn.

If you train a technical school, you can learn more systematically and understand the principle of mobile phones, so that no matter what mobile phones you produce in the future.

Independent maintenance, but you can learn the operation of mobile phone maintenance faster in the shop (of course, the premise is that the master can take the time to teach you)

But many problems don't understand what the principle is, and the new mobile phone is difficult to maintain.

If you want to learn, you can go to Guangzhou Crazy School, where the teachers are strict and the tutorials are reasonable, and you can learn a lot.

It is worth recommending.

What major does computer maintenance belong to?

Computer maintenance industry refers to the maintenance and repair of software and hardware problems in the use of desktop notebooks and the replacement of damaged hardware. This industry needs sufficient cultural knowledge accumulation and strong hands-on ability.

First-class maintenance

First-level maintenance, also called board-level maintenance. Its maintenance object is a device or a component in a computer, such as motherboard, power supply, monitor and so on. , including computer software settings. At this level, the maintenance method is mainly to locate and eliminate the faulty components or equipment through simple operations (such as replacement and debugging).

For example, there is a computer that does not display anything when it is turned on. As a first-level maintenance, it is necessary to determine whether this phenomenon is caused by the monitor, or the graphics card or even the motherboard. As long as the faulty component is identified and replaced, the maintenance task is completed.

Secondary maintenance

Secondary maintenance is a kind of maintenance for components and equipment. It is through some necessary means (such as testing instruments) to locate the faulty components and devices in parts or equipment, so as to achieve the purpose of troubleshooting.

For example, in the last example, if it is secondary maintenance, it is necessary to judge not only which component it is, but also which device or component on the component is faulty, and repair the faulty component, so as to complete the maintenance task.

Three-level maintenance

Three-level maintenance, also called line maintenance, is to repair the fault on the circuit board. Again, if it is not displayed due to line design or line fault, it needs three-level maintenance personnel to repair it. These people are usually system designers and developers.

What is the major of computer maintenance and what kind of school should I go to?

It belongs to computer specialty and hardware category. You should go to a computer professional training college or a computer professional maintenance school. If you want to get a junior college or undergraduate diploma, you can choose a computer training college, and you can also get a relevant junior college or undergraduate diploma after graduation.

What is the major of computer maintenance and assembly?

Repairing and assembling computers is a major of "hardware maintenance".

Hardware maintenance includes five aspects:

1.PC motherboards and graphics cards are relatively easy to be damaged. The general design life is about three years, and some products will be damaged even if they are used for more than one year. After losing the manufacturer's warranty, many users need maintenance. More importantly, the architecture of PC platform is changing rapidly. If the motherboard is not repaired, it is likely to change the CPU and memory, and it is difficult to buy a motherboard with the same interface. At this time, maintenance is almost the only choice.

2. Hard disk maintenance

Hard disk maintenance has always been one of the main businesses in PC maintenance industry. Because the hard disk itself is extremely unstable, its design life is short, and it is vulnerable to external shocks, so the damage rate has always been high. Although the price of hard disk is relatively cheap now, many users still hope to repair it successfully after discovering that the hard disk is damaged, so as to continue to play the residual heat. More importantly, many hard disks can still be used normally after repair, such as firmware damage and circuit board damage.

3. Notebook maintenance

Notebooks are expensive and relatively integrated. After losing the manufacturer's warranty, users can only turn to professional maintenance service providers. Relatively speaking, notebook maintenance costs are high, and replacing accessories has considerable profits. At present, many notebooks in China are only guaranteed for one year, and the services provided by manufacturers after the warranty period are not only expensive but also complicated, which leaves sufficient market space for our franchisees.

4. Peripheral maintenance

Printers are costly equipment. There is naturally a great market space for operating the maintenance business of these equipments. More importantly, the maintenance of these equipment can be combined with the sales of consumables, combined with some recycling technologies of consumables, and the profit is very objective.

5. Network maintenance and IT outsourcing

With the in-depth development of China's informatization, IT applications will be more extensive, the IT systems of enterprises will become more and more complex and diverse, and the speed of system updating and upgrading will be faster and faster. This makes IT difficult for many enterprises, especially small and medium-sized enterprises, to equip IT talents with comprehensive skills to organize and support the operation and maintenance of their IT systems. Moreover, due to the narrow IT application system, it is difficult for a single enterprise to retain high-quality IT talents. Faced with this dilemma, the mature IT outsourcing service in the procurement market has become the most realistic choice for such enterprises. With the help of the professional service ability of IT outsourcing service providers, enterprises are expected to achieve better cost control, apply the latest IT technology to their own IT systems, and realize the seamless connection between IT systems and their own businesses. IT can be seen that the huge difference between the IT resources and capabilities of small and medium-sized enterprises and the increasingly popular and important IT applications provides a broad space for the development of China's IT outsourcing service market. In particular, small and medium-sized financial institutions such as securities, funds, insurance, city commercial banks, small and medium-sized manufacturing enterprises, circulation enterprises and * * * departments will all become important users of outsourcing services.

In addition, the maturity of information technology and the improvement of network infrastructure have laid a material foundation for the development of IT outsourcing services in China. The maturity and transparency of information technology have promoted the super division of labor and integration of the information industry worldwide, and enabled independent third-party IT outsourcing services to be carried out smoothly.

Which major is computer maintenance?

Computer maintenance is the foundation in our school, and students of any major need to be able to maintain computers, whether it is design, website development, operation or other majors. But a little deeper, it is hardware. That's the network engineering major.

What is the major of computer maintenance?

Computer maintenance is mainly divided into these two aspects, mainly!

Board level maintenance

Board-level maintenance, the maintenance object is a device or a component in the computer, such as motherboard, power supply, monitor, etc. , including computer software settings. At this level, the maintenance method is mainly to locate and eliminate the faulty components or equipment through simple operations (such as replacement and debugging).

For example, there is a computer that does not display anything when it is turned on. As a first-level maintenance, it is necessary to determine whether this phenomenon is caused by the monitor, or the graphics card or even the motherboard. As long as the faulty component is identified and replaced, the maintenance task is completed.

It usually takes several weeks to learn board-level maintenance. Board-level maintenance is the lowest-level specialty in the whole computer industry. Chip level maintenance

Chip level maintenance is the maintenance of components. It is through some necessary means (such as testing instruments) to locate the faulty components and devices in parts or equipment, so as to achieve the purpose of troubleshooting.

For example, in the last example, if it is chip-level maintenance, it is necessary to judge not only which component it is, but also which device or component on the component is faulty, and repair the faulty component, thus completing the maintenance task.

Chip-level maintenance takes a month or two to learn. Chip-level maintenance has been the highest level of personal computer maintenance technology, whether it is desktop maintenance or notebook maintenance. In terms of technical content, it is actually not much higher than the technical level of various household appliances such as televisions, air conditioners and refrigerators.

I want to study computer maintenance, but I don't know what to major in.

Ask: Is it software engineering or software technology? Are these two the same thing? Answer: Oh, then learn software technology. After learning software technology, I can engage in computer operation and maintenance, network technology, web page design, website maintenance, network program design, network engineering and so on. , and can design, install and debug computer local area network; System integration of computer network communication products; Management and maintenance of WAN; Design, development and application of network management information system, website design and development, etc. Supplement: Computer maintenance belongs to computer hardware specialty, but there is generally no computer hardware maintenance course in computer specialty of regular colleges and universities. Instead, it is a professional training class, and some will have a chip-level maintenance major. However, students are required to have basic knowledge of electronic circuits, such as electronics and electricians, digital circuits and analog circuits. Without a certain foundation, it will be more difficult to learn and it will be difficult to accept such professional knowledge. In addition, the basis of computer maintenance is software maintenance, because we must first eliminate the factors of software failure, in order to determine whether it belongs to hardware damage, and get twice the result with half the effort. So learn software technology. Software engineering Software engineering is a systematic method to develop, run, maintain and repair software. One can be related to office automation, computer installation and maintenance, web page making, computer network and professional server maintenance and development, dynamic business website development and management, software testing and development, and computer-related equipment commodity trade. Supplement: well, in short, both will do. What is more developed in the future is software technology. I hope I can help you.

What major does computer maintenance belong to?

You don't have to go to those computer training schools. You still can't learn anything useful when you go out. You'd better see if there is an electronic market in your city. If there is any work in it, go in and work for them. If I have the conditions to surf the Internet, I will look at this knowledge online every day. If you really don't understand, you can ask an expert in the electronic market. Don't look at the advertisements of training schools for quick success and instant benefit. Everything will accumulate over time. Work in the electronic market for two years to ensure your first-class level.
