Telegraphy
Telegraph is the long-distance transmission of messages without the physical exchange of an object bearing the message. Thus semaphore is a method of telegraphy whereas pigeon post is not. Telegraphy requires that the method used for encoding the message be known to both sender and receiver. Such methods are designed according to the limits of a the signalling medium used. The use of smoke signals, beacons, reflected light signals, and flag semaphore signals are early examples. In the 1800s, the harnessing of electricity brought about the means to transmit signals via electrical telegraph. The advent of radio in the early 1900s brought about radiotelegraphy and other forms of wireless telegraphy. In the Internet age, telegraphic means developed greatly in sophistication and ease of use, with natural language interfaces that hide the underlying code, allowing such technologies as electronic mail and instant messaging.
