What do you mean by telegram?

Sending a telegram means sending one or more messages to the receiver by telegram. In the era when there are no modern communication tools such as smart phones and e-mails, telegraph is a very important communication method. When sending a telegram, you need to fill in the name, address and information content of the recipient. Postage is generally calculated by the number of words, and telegrams are fast and can be delivered soon. Although telegraph is rarely used now, its importance in history cannot be ignored.

The British Cook and Wheatstone first invented the telegraph in 1837. Later, after improvement, telegraph became more and more popular and became an international communication mode. During World War I, telegrams were used to transmit military information, war instructions and so on. Although the use of telegraph has decreased now, it is still very useful in some scenes. For example, some important international conferences still use telegrams to convey important information.

With the development of modern communication technology, the telegraph is gradually replaced by the Internet. Now, we can exchange information quickly through SMS, email and social media, which are more convenient than telegrams. The advantage of telegraph lies in its high transmission speed, and it is still used as an official communication form in some special occasions. In any case, the telegraph is an indispensable historical heritage, leaving a strong mark on the road of scientific and technological progress.
