19世纪三十年代，英国的库克和惠斯通开发了电报系统。该系统有五个磁针，通电后，可以指出一组字母和数字。
In the 1830s, the British team of Cooke and Wheatstone developed a telegraph system with five magnetic needles that could be pointed around a panel of letters and Numbers by using an electric current.
电报通常都用大写字母打出。
后来的电报机能自动解译字母和数字。
Later versions of the telegraph could decipher letters and Numbers automatically.
这样，电报机操作员就可以发送和接收拼成词语的字母。
In this way, telegraph operators could transmit and receive letters that spelled words.
1832年摩斯为电报系统勾画出了轮廓，1835年他研制出一套代表字母和数字的代码(摩斯密码)。
In 1832 Samuel F. B. Morse made sketches of ideas for a system of electric telegraphy, and in 1835 he developed a code to represent letters and Numbers (Morse code).
