Today, I would like to talk to you about what the work of IT is, many people may not know much about it. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something from this article.

The IT industry covers a wide range, including at least four categories: hardware, network, software and information systems, so the industries in these four categories, as well as personnel engaged in design, maintenance, support and management, form a ubiquitous IT industry.

IT main occupation

1. Software category: system analyst, computer programmer, software tester, software project manager, system architect.

2. Hardware: computer maintenance.

3. Network category: network engineer, network system designer, network integrated cabler, network construction engineer.

4. Information system category: computer operator, information system security division, information system manager, database system administrator, information system supervisor, information system evaluator, information resources development and management personnel, information system designer.

5. Manufacturing category: semiconductor device tester, semiconductor device manufacturing technician, semiconductor device manufacturer, semiconductor device support worker, semiconductor device packaging worker.

Hot posts in IT

1. Network engineer

Network engineer can be said to be a "green evergreen" profession, and network technology has always been in urgent need. According to the third quarter IT recruitment index and skills report of American human resources company RobertHalfInternational, network management ranks second in the overall demand for skills.

For the era of cloud computing, network plays a more important role in the cloud resource pool (computing, storage, network).

On the other hand, with the rapid development of IPv6 standard, Internet of things and mobile Internet, there are more and more talents and skills for network engineers, especially for new network engineers (mobile, IPv6, cloud computing).

As a result, network engineers can be subdivided into multiple development directions, and the corresponding skills require different emphasis. Such as network security, network storage, architecture design, mobile network and so on.

2. Algorithm engineer

Dr. he Wanqing has introduced three ways to get a thing done quickly, including "improving pipeline efficiency, better algorithms and shorter code critical paths." It can be seen that the algorithm plays an important role in system efficiency.

The algorithm is to let the machine solve the problem in the way conceived by human beings. The algorithm largely depends on the type of problem and the engineer's understanding of machine programming, and its efficiency is closely related to the algorithm.

In mathematics and computer science, algorithm (Algorithm) is a concrete step of calculation, which is often used in calculation, data processing and automatic reasoning.

In the era of big data, the function and function of the algorithm have been further highlighted. For example, for the company's search business, the development of search correlation algorithm, sorting algorithm. The data mining algorithm is designed for the massive user behavior data and user intention of the company.

According to the research field, the algorithm engineer is divided into audio / video algorithm processing, two-dimensional information algorithm processing in image technology and one-dimensional information algorithm processing in communication physical layer, radar signal processing, biomedical signal processing and so on.

In addition, data mining and Internet search algorithms, which reflect the development direction of big data, are becoming more and more popular in recent years, and algorithm engineers are gradually moving towards the direction of artificial intelligence.

3. Business intelligence analyst

The business intelligence extended by algorithm engineers has become hotter, especially in the field of big data.

Bluewolf, an IT career and consulting service, has reported that the fastest growing demand for IT jobs is in mobile, data, cloud services and user-oriented technicians, including business intelligence analysts.

Business intelligence analysts often need to be proficient in database knowledge and statistical analysis, and be able to use business intelligence tools to identify or monitor existing and potential customers.

Collect business intelligence data, provide industry reports, analyze technology trends, determine future product development strategies in the market or improve sales of existing products.

Business intelligence and logical analysis skills are particularly important in big data's era. IT talents with business knowledge and strong data and mathematical analysis background will be more favored by large enterprises in the future IT workplace.

However, these skills are not available to the average person, and some companies are currently recruiting statisticians and teaching them about technology and business.

4. Data mining engineer

A data mining engineer can also be called a "data mining expert". Data mining is a technology to find its rules from a large amount of data by analyzing each data.

Data mining is a decision support process, which is mainly based on artificial intelligence, machine learning, pattern recognition, statistics, database, visualization technology, etc., to analyze enterprise data and make inductive reasoning.

Dig out potential patterns to help decision makers adjust market strategies, reduce risks and make correct decisions.

The skills acquired by data mining experts or data mining engineers can quickly create wealth for them.

The data mining company founded by David Sallinger, Amazon's first data mining engineer, sold a product recommendation engine system similar to Amazon to online retailers and advertising sellers.

This product recommendation engine system has also become the most profitable tool in Amazon's history. This shows the value of data mining.

5. Consultant

Any business unit and any industry enterprise, there are IT systems behind the unknown support.

In the era of cloud computing big data, the challenges and opportunities faced by the business will also bring more requirements to the IT system. In this case, the planning, deployment, operation and maintenance of the IT system must have more proficient professionals to be competent, and meet the needs of big data analysis and cloud computing service applications in the future.

6. Mobile application development engineer

Mobile application development will become more popular with the advent of the mobile Internet era.

By the end of 2012, China has 1 billion mobile phone users and more than 400 million mobile intelligent terminal users. A large number of mobile Internet games, applications and start-ups have emerged in mobile payment, mobile shopping, mobile tourism, mobile social networking and other aspects.

There are many intelligent systems on mobile platform, but the ones that are really influential are iOS, Android, WP, Blackberry and so on.

A large number of original PC and Internet information applications and Internet applications have appeared on the mobile phone platform, and some novel applications that have never been seen before have also begun to appear and increase day by day.

7. Software engineering designer

In recent years, the IT industry has gradually emerged a wave of software-defined network (SDN), software-defined data center, software-defined storage (SDS) and software-defined server (MoonShot). There is a trend that software defines all future IT infrastructure.

8. Database development and management

Database development and management is particularly important in the era of big data. The related database management, operation and development technology will become the skills that the majority of BI, large enterprises and consulting and analysis institutions pay special attention to.
