IT industry cooperation organizations, 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 expressway 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.
