-Sensing technology This is the extension and expansion of human sensory organs, and the most obvious example is the bar code reader;
-Communication technology, which is the extension and expansion of human nervous system, undertakes the function of transmitting information;
-Computer technology This is the extension and expansion of the function of the human brain, which undertakes the function of processing information.
The so-called informatization is to transform other industries and industries with information technology, so as to improve the efficiency of enterprises. In this process, information technology plays the role of a powerful tool.
By the way, what is the IT industry? There is a general classification for your reference:
Provide IT basic technology, ic research and development, software writing, such as INTEL, MS, etc.
IT technology productized parts, components, assembly manufacturing such as elite, Volkswagen, etc.
IT products integrate computer and peripheral manufacturers such as Lenovo and IBM.
Systematic solutions and information systems for IT products such as Huawei and Hewlett-Packard.
Distribution channels and sales of IT products, such as Digital China.
Blue Express and other IT products, services, consulting services and after-sales services.
Public opinion in IT industry supports IT media such as World Plan Information and CCID.
The third party in IT industry provides various matching services, such as legal consultation and public relations services.
It trains reserve talents in various colleges and universities such as computer specialty.
The IT industry cooperates to organize various associations and parties.
IT (information technology) has become a common technology in all industries in the 2 1 century, because any management activity is inseparable from the trust in information.
Material, energy and information constitute a system, and information is an essential element of all systems. It's not that there is information after the computer appears. We can feel the existence of things or imagine the relationship between things because information acts on us. There are countless kinds of original or hidden information in the world. It is precisely because of the differences of these types of information that we can distinguish different substances with our senses.
If the way of carrying information is as different as its content, just as the span of a railway varies from car to car, we can't build an information superhighway to transmit and process this information. This is also the most basic problem it has to solve. The content and form of information, like the relationship between "car" and "goods", unify the standards of cars, roads and bridges, solve the standards of goods packaging and transportation, and improve the efficiency of logistics industry.
It is a tyrant of reform for different industries that use it. It forces us to constantly learn, invest, reform our working methods and even completely change our view of the world. In fact, another form of the real world, "virtual world" or "digital world" is taking shape. Maybe this is antimatter. However, the foundation of this world is unified, and its emperors are storage kings such as Microsoft, IBM and Intel.
When importing IT strategy, the following problems are inevitable:
First of all, what are its technical advantages compared with traditional methods?
The processing methods of information flow have experienced manual recording, ancient "knotting record", mechanical calculation (such as abacus and hand calculator), electronic calculator, microcomputer, server computer and real-time data processing system.
The traditional method, in a word, is the method of "simulating" the actual object, and then applying digital logic to get the result. Among them, the form of numbers has not changed, at most, logical operation marks (such as algebraic letters) have been introduced, or physical objects (such as abacus beads) have been replaced, so the application is limited by this "physical" shape, and the operation speed and transmission are seriously restricted by time and space.
The method of electronic computer is "virtual", the "object" in operation is shielded, and the quantitative relationship is simplified as "on-off" of the circuit, that is, "1 and 0" that the machine can appear or recognize. The quantity and operation of anything are expressed by the logical relationship of "0 or 1".
From this point of view, the method of electronic computer is a bit like the research methods of "physics" and "chemistry", that is, breaking things down into the smallest elements and then defining their properties. Modern physics finally decomposes matter into "six" elements, and the whole world is made up of these elements.
Computer method, that is, information method, also coincides with the information of "genetics". There are also two information elements in biological reproduction: X and Y chromosomes. Information can be copied endlessly across the boundaries of time and space. It is with this invisible digital form that everything can be expressed by this code in the digital age. Any relationship in the real world is a "digital relationship", and there is no formal difference in computers. Therefore, we firmly believe that digitalization is the fundamental way to unify and fully automate our real world.
Informatization will be a brand-new world, which will change our thinking and philosophy of life.
Second, the difference between automation and digitization
When it comes to "mechanization" and "automation", a literate person can imagine what they are, but "digitalization" or "e" is different. Only those who understand it can know its essence.
The former and the latter are not the same in methods and operations. Automation in analog form is a closed and isolated event, and only digitalization is an open system, that is to say, things expressed and operated digitally can have powerful functions, especially intelligence. The movement and change of things, from the information point of view, are systematic engineering of information generation, storage, transmission, conversion, processing, operation, renewal, replacement and exchange. The means to successfully complete this process is the information flow control program.
The only way to truly "automate" is to rely on a system based on "digitalization" (a project combining software and hardware).
Third, the digital future
"Digitalization" is a "natural trend" and has no national boundaries or nationalities. No matter who invented it, the laws of numbers are used for science. After half a century of human efforts, "standards and tracks" have been formed. Just as human hands are ten fingers, we can create the world with our hands. If we are keen on patriotism, we can make our hands into 12 fingers, but this is not accepted by biology.
Informatization is also "globalization". In this world, the more we talk about national boundaries, the more painful it is. You are helplessly "painful and happy". It's better to stand up and walk with you after being towed away. It will make you feel better.
When I was studying philosophy, I came across a proposition: the world is unified in matter. In the "digital age", we inevitably repeat another proposition: the world is unified in "1 and 0". They don't stand for "America or Russia", but just the code of information.
In fact, in addition to "cultural, economic and military" forces, we have found a fourth element that can unify the world, and that is "digital technology".
Because numbers, like "water", are undifferentiated, standardized and fluid, they are also necessary. The basic conditions when it flows are also universal, and its "internal" unity determines that people who use it must carry out activities in the same "virtual space".
The founders of this field: IBM, Microsoft, etc. At present, he is the overlord of this world. In a sense, they are already IT leaders. If you don't want to be their followers, you have to set up another portal, such as Linux, but it is difficult to have enough followers.
The biggest beneficiary of digitalization is also its innovator, but without digitalization, it is "waiting for death".
The benefits of digitalization to the public are self-evident. It is eliminating the inequality of information, wealth and identity. Network communication, distance education and programming tools all give equal rights to participate or create.
A kind of civilian culture is "coming" with the advancement of "informatization".
Fourth, what is the import process?
Judging from its technical principles and specifications, no one can keep it for himself. But when we walked into this IT castle, we found that we seemed to have entered a kingdom with a long history. The legal, urban, street, traffic and administrative systems here already exist. Our job is to constantly copy the things in this "castle" and find a free space-"custom" way, but there is room for breakthrough.
Every few years, the castle will have new management methods and new tools, and some strange ingredients will be added to new products. IT people and people who apply IT are always following the trend of "fashion". In other words, the process of digitalization is a process of "learning from western IT soft and hard companies", and at the same time, it is also a process of rapid layoffs. In this process, the amount of capital or assets controlled by everyone will rise sharply, and the demand for compound, highly educated and white-collar talents will increase year by year. If a country with a population of one billion faces such "digitalization", it will face serious talent shortage and overpopulation. However, "digitalization" is inevitable. At the level of civilization, it will improve production efficiency and eat competitors from profits; Militarily, it means a fatal blow to the opponent.
What kind of IT technology is the most valuable?
-
In today's IT industry, many technologies are short-lived. When it was first introduced, it was full of enthusiasm and looked promising, but soon newer and better technologies appeared again and had to learn again. So should we think carefully, in the current IT industry, what kind of IT technology can make you work hard all your life, and the older you are, the more valuable you are?
Some simple application-based and tool-based technologies are updated very quickly and easy to learn and use, so they are of little value to the career of IT professionals. Just knowing some conventional technologies such as windows installation, IP address configuration, router configuration, etc., can't bring a leap in salary or technology.
In the process of job hunting, IT technicians often see that the job requirement is at least 35 years old, which may also be determined by the current IT situation in China. At present, the basic situation of TI industry is a surplus of talents, but the surplus is only non-shortage talents who master low-end technology. In the high-end field, talents who master high-end technology are always lacking.
Then, according to the current situation of the IT industry, we can judge which technology is the field with the greatest demand for talents, and the technology will last longer. UNIX/Linux platform technology is very professional. In the 30-year history of the birth of UNIX system, many technicians of UNIX platform are full of white hair. If you think you are smart enough to find a job with a salary of not less than RMB10000 within three years, and you are very professional and can do it all your life, then the system technology, network technology, security technology or development technology of UNIX/Linux platform are very suitable for you to learn.
Then you must ask, what is the talent demand in the field of UNIX/Linux platform now? In fact, the simplest and most effective way to understand the talent demand in this field is to directly log on to the recruitment website (if you want to recruit in the future) and enter linux keywords in the search location. We don't need to search the recruitment situation for a long time. We just need to select the information about linux jobs released on the same day, and we can intuitively see the relevant information such as talent demand, salary and treatment.
Let's briefly introduce the field of UNIX/Linux platform.
UNIX/Linux is the most widely used platform in IT field, and more than 90% of DNS servers in the world are built on UNIX or Linux platforms. Less than 10 of the world's top 500 supercomputers run on Windows, and most supercomputers run on customized UNIX/Linux systems. Google, a world-famous search engine, has a cluster of nearly 18000 Linux servers.
Linux is a UNIX-like operating system and a variant of UNIX operating system. They are related and are the most dynamic operating system at present. It has open source code and is supported by many multinational enterprises and governments. For example, the main platform of database products in Oracle Bone Inscriptions is Linux, and the China government uses Linux in large quantities when purchasing operating systems.
The particularity of UNIX/Linux system determines that many people can't master the system quickly, and the road of self-study is very long. Generally, the salary level of UNIX/Linux posts is higher, because there are fewer IT professionals who have reached the level, and many systems are out of reach of ordinary people. At the same time, the UNIX/Linux training level of many training institutions can't meet the entry requirements, because the level and experience of teachers are not enough, so it is not easy to find expert professional training institutions.
I solemnly remind you that there are some skills in choosing a training institution wisely. Don't listen to authoritative and prestigious schools. Teachers from Tsinghua of Peking University seldom come to the training center to teach, so you must communicate with the head teacher and listen to them.
Shangguan Technology has carried out various technical trainings on UNIX/Linux platform at the real professional level, and recruited many UNIX/Linux platform experts, such as experts who are proficient in Red Hat Linux cluster suite, Shangguan Linux research room composed of seven RHCE (Red Hat Certified Engineers), UNIX/Linux platform Oracle database experts, Linux kernel developers, etc., to create a wonderful UNIX/Linux career for you.
At present, the courses offered are ULP for UNIX/Linux expert training, including mastering Linux system, Solaris system (a UNIX system), Linux tuning (exclusive), Linux cluster (exclusive), Oracle database 9i and 10g under UNIX/Linux platform, and even RAC (Oracle real application cluster).
In addition, there is kernel and driver training for UNIX/Linux C development direction. As long as you are smart enough, Shangguan Technology will start your career in the next 20 years.
