What is a phone?
The question of what a phone is, it may seemmodern man is naive and even funny. Today these devices are used by everyone, including children of kindergarten age. And technical ideas embodied in the usual "tube", few people care. Although the history of the development of telephones is quite long: in the first century of our era there were primitive apparatuses for transmitting sound over some distance.
origin of name
As in most cases, the term was Greek. In artistic translation into Russian it will be "far-talking"; in the subscript - two words "far" and "sound" ("voice").
Meanwhile, by showing your mobile on the question of what a phone is, you will give a somewhat one-sided answer. Initially, the term had two meanings:
- The whole engineering system for voice transmission;it was assumed that the technical devices include (and, accordingly, the concept of what a telephone is) wires, commutator, etc. And, this definition of the phone was the main one. Now, probably, in this sense, the phone includes cellular towers.
- The second thing that falls under the definition of the phone is the device itself, through which conversations are conducted. In the modern world, perhaps, this understanding completely replaced the former.
It is curious that in the detailed definition of the phone, the signal transmission paths are also indicated: "air, cable and microwave links". At the same time, no one will ever think of calling a radio a phone.
And the history of the development of "telephone business" can be read in the publication Who invented the phone.
