How do I send a telegram?

Sending a message via telegraph

Before the invention of the telegraph, communication between people who were separated by distances was carried out by sending messages, or traveling to meet them, but after its invention, people were able to send across hundreds and thousands of miles within about an hour, and after the spread of telegraph stations in major cities by the fifties of the nineteenth century, it became Its workers send messages, receive them, translate their encrypted codes, and then deliver them to the manual couriers (message senders). The process consisted of sending certain signals over wires based on the Morris Code, which linked his code to different patterns of letters of the alphabet that were clicked to send messages. It was transmitted via telegraph cable. The telegraph was initially used to connect the city of Baltimore and Washington, D.C., in 1843 AD.

Telegraph

Telegraph is any system or device that allows the transmission of information across distances through encoded signals. Several telegraphic systems have been used over the centuries, but the term telegraph is usually used to refer to the electric telegraph that was developed in the nineteenth century, as it was the primary means of transmitting printed and portable information. Through wires or radio waves for at least a hundred years, the word telegraph was derived from the Greek language, which means writing at a distance. The credit for its invention goes to Samuel Morris, who began working on the electric telegraph in 1832 AD after he invented his own code in 1830 AD, to culminate in His efforts were finally granted a patent in 1837 AD.

The idea of ​​inventing the telegraph

While Morris was on his way back to his home in 1832 AD, he discussed with several scientists about the relationship between the speed of transmission of electric current passing through a conducting wire and the length of that wire. One of them said: Electricity passes instantly through the conducting wire, regardless of its length, by relying on On the experiments of the scientist Franklin, this discussion was the first spark for the emergence of the idea of ​​inventing the electric telegraph by Morris.

Uses of the telegraph in ancient times

The telegraph enabled people to transmit messages over long distances from one place to another through electrical networks. It also helped several government and media agencies transmit news, in addition to linking America with the continent of Europe. The practical importance of the telegraph became clearer in 1846 AD when the news agency was established. Associated Press, as it used the widespread telegraph lines to send news messages to newspaper offices, and collect the results of the American elections in 1848 AD.

The end of the telegraph era

Modern technology became available after World War II, which led to a radical change in the telegraph industry. The old wire lines were replaced by coaxial cables and microwave connections. Electrical transmission media then increased further to include optical fibers and satellites. The telegraph was also finally replaced by digital data transmission systems. Which depends mainly on making use of computer technology.
