What happened to the failure of sending SMS by CITIC Bank?

There may be the following reasons for the failure of sending SMS from CITIC Bank:

Personal use of mobile phone signal is not good;

There may be a mobile phone arrears;

Need to set the SMS function;

There are other technical problems. After excluding the first three, you can call the mobile phone operator or the customer service hotline of China CITIC Bank for help.

Information refers to the objects transmitted and processed through audio, news and communication systems, and generally refers to all the contents spread by human society. People can distinguish different things by obtaining and identifying different information from nature and society, so as to understand and transform the world. In all communication and control systems, information is a common form of communication.

1948, the mathematician Shannon pointed out in his paper entitled Mathematical Theory of Communication that information is used to eliminate random uncertainty. The most basic unit of creating everything in the universe is information.

Although the information is uncertain, there are ways to quantify it. According to the concept of information, people can conclude that information has the following characteristics:

The greater the probability P(x) of message appearance, the smaller the amount of information; Conversely, the smaller the probability of occurrence, the greater the amount of information. As you can see, the amount of information (which we refer to as I) is inversely proportional to the probability of message occurrence.

When the probability is 1, everyone in the world knows what happened, so the amount of information is 0.

When a message consists of several independent small messages, the information contained in this message should be equal to the sum of the information contained in each small message.

scientific terminology

Josiah Willard Gibbs, a famous American physical chemist, founded vector analysis and introduced it into mathematical physics, which found a new angle for studying the uncertainty and contingency of events, thus making mankind take the first step in grasping information scientifically. He believes that "entropy" is a measure of the lack of information in physical systems.

Electronists and computer scientists believe that "information is the content transmitted in electronic circuits with signals as the carrier".

Professor Zhong Yixin, a famous informatics expert in China, believes that "information is the way of existence or the state of motion of things, which is directly or indirectly expressed in this way or state".

American information management expert F.W.Horton defines information as: "Information is processed data to meet the needs of users' decision-making. "Simply put, information is processed data, or information is the result of data processing.

According to the research results of information. The scientific concept of information can be summarized as follows:

Information is the reflection of the movement state and change of various things in the objective world, the representation of the interrelation and interaction between objective things, and the representation of the movement state and change essence of objective things.

Physically speaking, information and matter are two different concepts. Information is not matter. Although the transmission of information requires energy, information itself has no energy. The most striking feature of information is that it cannot exist independently, and the existence of information must depend on the carrier.
