2. Modern: wired communication transmission, telephone, fax, telegram, television, etc. Wireless communication transmission, interphone, mobile phone, radio. Digital communication transmission, Internet, digital TV. Paper communication transmission, letters, newspapers, etc.

"bonfire" is a communication method used to transmit frontier military information in ancient China. It began in Shang and Zhou Dynasties and extended to Ming and Qing Dynasties. It has been learning from each other for thousands of years, especially in the Han Dynasty. At the height of the frontier defense military fortress or traffic hub, a high platform is built at regular intervals, commonly known as beacon tower, also known as beacon tower, pier, smoke pier and so on.

Modern communication-network, as a fast communication method, is more and more accepted. Like a mailbox, as long as you click the mouse, your friends will receive your email within a few seconds.

Another example is chat tools such as QQ and MSN, which are also accepted by people. At the same time, because this transmission method is based on virtual digital transmission, the higher the new one, the easier it is for information to collapse. Even if it is often backed up, it can't resist the hacker attack of data overflow. At the same time, because of its fast transmission speed, it is easy to spread wrong and restless information quickly.

expanding information

in ancient times, China used drums to transmit information, as early as the end of the primitive society in the 195s. By the Western Zhou Dynasty, China had a relatively complete postal system. ?

during the spring and autumn period and the warring States period, with the progress of politics, economy and culture, postal communication gradually became complete. During the Three Kingdoms period, Cao Wei's greatest achievement in the history of postal service was the formulation of the Postal Service Order. ?

One of the signs of the development of postal services in Sui and Tang Dynasties is the increase in the number of post offices. During the Yuan Dynasty in China, postal service developed greatly. The biggest feature of the post system reform in Qing Dynasty is the combination of "post" and "post". After the middle of the Qing Dynasty, with the establishment of modern postal service, the ancient postal system was gradually eliminated.
