What are the differences between the modern way of transmitting information and the ancient way?

There are the following differences between ancient and modern ways of transmitting information:

1. Differences in tools for transmitting information: In ancient times, because of the long distances and inconvenient means of transportation, it was extremely inconvenient to transmit information quickly. The only tool for transmitting information is horses (the state transmits information), and private information is conveyed by pedestrians, caravans, and friends who are entrusted to go to the place where the information is received. In modern times, encrypted computer information transmission (state transmission information) is used, while private transmission is through phone calls, emails, online chats, etc., which is convenient and fast.

2. Differences in people delivering information: The ancient information carriers were mainly letters, which were carried by specialized people. For example, in ancient times, military and state affairs were urgently sent by eight hundred miles or six hundred miles, and were set up midway. The inn is used to transfer and exchange horses to increase the horse power and speed. However, people are not changed when horses are exchanged, and a dedicated person is responsible for it. Private individuals ask pedestrians, caravans, and friends to deliver the goods. Today, the military still has dedicated personnel responsible for sending and receiving information, because military and national affairs are confidential. Private information is transmitted by mobile communication companies, basic information transmitting stations, and electronic devices. Everyone can transmit information anytime and anywhere.

3. The difference in time for transmitting information: In ancient times, due to the underdeveloped transportation and the speed limit of transportation, even the fastest 800-mile express needed to travel from the place where the information was sent to the place where it was received. It also takes days, whereas private messaging is usually measured in months. Today, with the development of transportation tools and radio wave reception signals, the use of radio waves to transmit information can achieve instant reception and transmission.

Ancient methods of transmitting information: 1. Chicken-feather letter: generally used among the people. 2. Flying pigeons to send messages: migratory birds, especially pigeons and geese, are used as transmission tools. 3. Expressing letters by horse: a method of communication in which letters are delivered by horseback. 4. Bamboo tube: used by both officials and private citizens, similar to current envelopes. 5. Urgent delivery: running delivery, used to deliver urgent military information, commonly known as "passing gold medals". 6. Different dynasties such as beacon fire and beacon smoke have different transmission methods. 7. Convey information with special sounds, such as bells, drums, firecrackers, etc. 8. Ways of making fillings, such as hiding in fish maws, cakes, steamed buns, drift bottles, etc.

Modern methods of transmitting information: 1. Wired communication transmission: such as telephone, fax, telegraph, etc. 2. Wireless communication transmission: such as mobile phones, walkie-talkies, radio, television, etc. 3. Network communication transmission: such as email, video, QQ chat, etc. 4. Paper communication transmission: such as letters, newspapers, books, etc.
