Information is indestructible.Unlike objects and energy, information is indestructible. Both matter and energy are indestructible. Its form can be transformed, but the indestructibility of information is different from them.A cup is broken. The atoms and molecules of the ceramics that make up the cup have not changed, but they have not become a cup.Also like energy, we canelectric energyIt becomes heat energy, but after it becomes heat energy, there is no electric energy.The indestructibility of information is that after a piece of information is generated, its carrier can be changed and destroyed, such as a book or a CD, but the information itself has not been destroyed. Therefore, the indestructibility of information is a great feature of information.
2. Information has unlimitedReplication。It can be widely spread. Unlike the duplication of objects, the duplication of information is very cheap. One piece of information can be copied into one million pieces of information.Although the creation of information may require a lot of investment, replication only requires the cost of the carrier, which can be replicated in large quantities and spread widely.
3. Information hasDirectivity。The value of some information is very strongTimeliness。A piece of information is very valuable at a certain time, but after that time, it may not have any value at all.
financial information It will be very valuable when you need to know, but after this moment, this information will be worthless.Another example is the information in the war.
