What are the professional types and related positions of computers?

The classification of the IT industry is very detailed. Many friends are not very clear. Many friends want to enter the industry very much, but sometimes I do n’t know how to start. Here I throw a brick for everyone to criticize, discuss, and have the strengths of each other.
IT industry is generally divided into three aspects:
1. Network
2. Software
3. Integrated circuit
If you want to enter the IT industry, then you must first enter the enter One of these three aspects.
three aspects of employment direction:
1. Integrated circuit direction, this is a very professional direction, requires job seekers to have strong professional knowledge. These professional knowledge can be supplemented by training. It requires very much. Good ones are similar to the training of university education; this kind of talent has a narrow employment side, but if employment is employed, its salary is high (of course, depending on the situation of the company)
2. Software direction. It is relatively wide. A good software engineer also needs a solid mathematical foundation. Conventional training can make a person without software become a software blue -collar, but to become a software designer, it still needs a considerable work and study time; most of these talents are employed in software companies;
3. Network direction, this direction, this direction, this direction, this direction, this direction, this direction, this direction, this The noodles involved are much wider than the previous two. Through training, it may gradually become an engineer from a person who does not know about network technology, because network technology is a technology that is more biased towards operation. It is also much wider in employment, because informatization is a whole society’s project. The government and enterprises are conducting informatization. They all need to find appropriate talents in the network for its operation, management, and maintenance of their network systems.
Therefore, from the perspective of employment, network engineers> Software engineers> Integrated circuit engineers
Nowadays, society, schools, and enterprises have raised a software engineer to cultivate heat. This is a misleading. Indeed, we need it. A large number of software engineers, but the current training is just a kind of software writing personnel training. Whether the trainees will really become the dominant power of software development in the future are still a question. Leave it for these software Coding personnel?
is different, but network engineers need to be needed by all walks of life.
What is the network engineer, we can make some understanding from the corporate information -based post system. In the process of enterprise (or government) informatization, the following four types of people are required:
1. Informatization supervisor: responsible for the target and plan decision in information construction, the direction of informatization construction;
2. Engineering project Technical staff: Responsible for the design and construction of the informatization system, including the construction of equipment, systems, databases, and application systems;
3. Operating maintenance personnel: responsible for the operation, maintenance, management and basic development of the informatization system; r; r; r; n4. Operation application staff: Mainly applying information systems to do their job.
It, in the process of enterprise informatization construction and operation, an enterprise will give the construction process out of the outsourcing method to a professional IT company to complete it. Therefore, an enterprise will not have an IT system engineering and technical personnel. The engineering and technical personnel of the system are concentrated in professional IT companies; when the information system is completed, the enterprise generally has one person, or a group is responsible for the operation, maintenance, and management of the informatization system. From the perspective of cost, companies will recruit a person who knows about network equipment, network systems, databases, network management, network security, and basic network development to be responsible for its informatization system. Such people are generally called network management Essence The knowledge of such people is horizontal, many aspects, but not particularly professional. If the company really encounters very professional technical problems, it will generally allow this network management to consult IT companies with problems.
Serway, from this perspective, the employment of network engineers will be far greater than other two types of engineers.
It now there are many certification training or training certifications called network engineers in society. How do we choose? We can analyze and understand the system of network technology:
1. Network equipment technology, which mainly involves involved The hardware construction of the network, including routers, switches, bureau networks, and Guangwang. This aspect is representative of Cisco and NORTEL;
2. Network operating system, which mainly involves the system management and network management of the operating system. This The representative directions are Windows 2000, UNIX, Linux, etc.;
3. Network database, which mainly involves databases applied to the network. Everyone should not take the network security one -sidedly as the security of the operating system and application system. In fact, the security issues exist in all aspects of the network. In this regard, there is no better and comprehensive certification in China;
5 . Network management, which involves a comprehensive management, optimization, billing, etc. of a bureau network, Guangwang, and no comprehensive certification;
6. Network application development, basic development, interactive development of enterprise website The technology includes HTML, ASP, JSP, Java and so on.
These six aspects are necessary factor for enterprise informatization, so if you want to add your own knowledge, you can add it from these six aspects. , Or professional personnel. However, if you can lay a solid basic skills in this regard, then choosing a direction in your work will be even more powerful.
In short, everyone should step by step to determine their own direction, and then strive to enrich themselves in multiple directions
