1, the transmission channels are diversified, such as wired communication transmission (telephone, fax, telegram, television), wireless communication transmission (walkie-talkie), digital communication transmission (computer, mobile phone), paper communication transmission (newspaper, letter) and so on.
2. Transmission speed: The transmission speed of modern information is much higher than that of ancient times. In ancient times, the fastest way was to send books by flying pigeons or fast horses, which also took several days. But in modern times, the Internet can make information real-time.
3. Diversified transmission functions: In addition to the basic functions of data collection, transmission, storage and management, modern information transmission can also provide users with information services such as information retrieval, statistical report, transaction processing, planning, design, command, control, decision-making, alarm, prompt and consultation.
Disadvantages of modern information transmission:
1, involving privacy. Due to the fast speed and wide range of modern information transmission, it is very likely that some parties' information will be exposed to the network instantly, which may infringe on the privacy of the parties.
2, easy to be deceived. Due to the great convenience of modern information transmission, criminals are likely to take advantage of this to engage in illegal fishing, defrauding information, and winning fake prizes.
Extended data
The characteristics of modern information transmission are:
1, involving a large amount of data. Generally, data need to be stored in auxiliary memory, and only a small part of the data to be processed is temporarily stored in memory;
2. Most of the data is persistent, that is, it does not disappear with the end of the program, but needs to be stored in the computer system for a long time;
3. These persistent data are shared by multiple applications, even in a unit or a larger scope.
