Four basic characteristics of information

As long as there is material, there will be information, which is independent of human will.

(2) Dependence

All information does not exist out of thin air and must be attached to some kind of carrier, but the carrier itself is not information.

(3) Sharing

We all know that Liu Xiang retired due to illness. Just because you know, and I can't have this information.

(4) Value

Information is always valuable.

For example, the college entrance examination reform, this information is valuable to all of you here.

The value of information depends on the information needs of information recipients and their ability to understand, identify and apply information.

5] Timeliness

Miss Li saw a poster saying that clothes in department stores were sold at a 20% discount, so she happily went shopping in the building. But when she arrived at the building, Miss Li was very disappointed. It turned out that the building was a three-day discount promotion to celebrate the tenth anniversary of the opening of the store, and now the activity has ended.

In modern society, the use cycle of information is getting shorter and shorter, and the realization of information value depends on its timely grasp and application.
